+/// Unlike the standard Tokio semaphore, this implementation allows for reduction of the

+/// This is particularly useful for rate limiting scenarios where we need to dynamically
+/// adjust the concurrency level based on runtime conditions.
+///
+/// # Key Features
+///
+/// - **Dynamic Capacity Reduction**: Can reduce capacity even when permits are in use
+/// - **Queued Waiter Preservation**: Existing waiters remain in queue during capacity changes
+/// - **Thread-Safe**: All operations are atomic and safe for concurrent use
+/// - **Drop Safety**: Automatically manages capacity when permits are released

+/// ```rust,no_run

+/// async fn main() {

+# Integration Tests for Feroxbuster
+
+This directory contains integration tests for feroxbuster using real HTTP servers instead of mocks.
+
+## Auto-Bail Integration Tests
+
+The auto-bail functionality is tested against real servers to validate timeout and error handling behavior.
+
+### test_integration_caddy.rs
+
+Contains two integration tests for auto-bail with timeouts:
+
+#### 1. Python Server Test (`integration_auto_bail_cancels_scan_with_timeouts`)
+
+- **Purpose**: Tests auto-bail behavior with real timeout conditions
+- **Server**: Python HTTP server with 5-second delays
+- **Requirements**: Python 3 (usually pre-installed)
+- **Run**: `cargo test integration_auto_bail_cancels_scan_with_timeouts --test test_integration_caddy -- --exact --ignored --nocapture`
+
+#### 2. Caddy Server Test (`integration_auto_bail_with_caddy`)
+
+- **Purpose**: Tests auto-bail behavior using Caddy web server
+- **Server**: Caddy with connection termination for timeout paths
+- **Requirements**: Caddy web server
+- **Install Caddy**: 
+  ```bash
+  sudo snap install caddy
+  # or
+  sudo apt install caddy
+  ```
+- **Run**: `cargo test integration_auto_bail_with_caddy --test test_integration_caddy -- --exact --ignored --nocapture`
+
+## Test Structure
+
+Both tests follow the same pattern:
+
+1. Start a real HTTP server on a random port
+2. Configure server to delay/terminate connections for `/timeout*` paths  
+3. Create a wordlist with timeout-triggering and normal words
+4. Run feroxbuster with auto-bail enabled
+5. Analyze debug logs for timeout errors and auto-bail behavior
+6. Clean up server and temporary files
+
+## Why Integration Tests?
+
+While mock server tests provide controlled scenarios, integration tests offer:
+
+- Real network stack behavior
+- Actual timeout and connection handling
+- Validation against real server implementations  
+- Detection of edge cases not covered by mocks
+
+## Running All Integration Tests
+
+```bash
+# Run only Python-based test (no external deps needed)
+cargo test integration_auto_bail_cancels_scan_with_timeouts --test test_integration_caddy -- --exact --ignored
+
+# Run Caddy test (requires Caddy installation)
+cargo test integration_auto_bail_with_caddy --test test_integration_caddy -- --exact --ignored
+
+# Run all integration tests
+cargo test --test test_integration_caddy -- --ignored
+```
+
+## Expected Behavior
+
+The integration tests validate that:
+
+- Feroxbuster correctly generates timeout errors against slow servers
+- Auto-bail logic processes these errors appropriately  
+- The scan completes successfully (auto-bail doesn't cause crashes)
+- Debug logs contain proper error reporting and statistics
+
+Note: Auto-bail timing may differ between mock and integration tests due to real network conditions.

+//! Integration tests for feroxbuster auto-bail functionality using real HTTP servers
+//!
+//! This module contains integration tests that validate feroxbuster's auto-bail behavior
+//! against real HTTP servers, as opposed to mock servers. These tests are marked with
+//! `#[ignore]` by default because they require external dependencies.
+//!
+//! ## Available Tests
+//!
+//! ### `integration_auto_bail_cancels_scan_with_timeouts`
+//! Uses a Python HTTP server to simulate delayed responses that cause timeouts.
+//! **Requirements:** Python 3 (usually available by default)
+//! **Run with:** `cargo test integration_auto_bail_cancels_scan_with_timeouts --test test_integration_caddy -- --exact --ignored`
+//!
+//! ### `integration_auto_bail_with_caddy`  
+//! Uses Caddy web server to simulate connection issues.
+//! **Requirements:** Caddy web server
+//! **Install:** `sudo snap install caddy` or `sudo apt install caddy`
+//! **Run with:** `cargo test integration_auto_bail_with_caddy --test test_integration_caddy -- --exact --ignored`
+//!
+//! ## Why Integration Tests?
+//!
+//! Mock server tests are great for controlled scenarios, but integration tests with real
+//! servers help validate:
+//! - Real network timeout behavior
+//! - Actual HTTP server response patterns  
+//! - End-to-end functionality in realistic conditions
+//! - Edge cases that might not be captured in mocks
