+### Requirements
+
+- **PHP 8.5.0+**
+- **LibUV ≥ 1.44.0** (required) - Fixes critical `UV_RUN_ONCE` busy loop issue that could cause high CPU usage
+
+### Why LibUV 1.44.0+ is Required
+
+Prior to libuv 1.44, there was a critical issue in `uv__io_poll()`/`uv__run_pending` logic that could cause the event loop to "stick" after the first callback when running in `UV_RUN_ONCE` mode, especially when new ready events appeared within callbacks. This resulted in:
+
+- **High CPU usage** due to busy loops
+- **Performance degradation** in async applications
+- **Inconsistent event loop behavior** affecting TrueAsync API reliability
+
+The fix in libuv 1.44 ensures that `UV_RUN_ONCE` properly returns after processing all ready callbacks in the current iteration, meeting the "forward progress" specification requirements. This is essential for TrueAsync's performance and reliability.

Subject: [PATCH 18/24] #19: Fix race conditions and conflicts when running
 async tests with multiple workers:

       - Replace basic uniqid() with PID + microtime for unique temp files
       - Ensure each worker gets isolated temporary files and directories
       - Maintain cross-platform compatibility (Windows + Unix)
       - Preserve existing API - no breaking changes to test files

       This resolves "Server did not output startup message" failures when tests
       run in parallel with -j option.
