Pull Request Overview

This PR addresses potential borrow_mut panics in the nginx module by replacing direct borrow_mut() calls with try_borrow_mut() to handle re-entrant access gracefully. The changes improve robustness by adding null pointer checks and fixing some minor timing and event handling issues.

• Replaces borrow_mut() with try_borrow_mut() to prevent panics on re-entrant calls
• Adds null pointer safety checks in callback functions
• Fixes timer handling and event management logic
