Description: after_forkers_child.lock() can deadlock in the forked child if another thread held the mutex at the time of fork. Use try_lock and skip at-fork callbacks when the lock is unavailable, matching the pattern used in after_fork_child for thread_handles. Summary by CodeRabbit Bug Fixes Safer handling of fork callbacks to ensure after-fork callbacks run reliably in child processes. More robust environment construction for exec/execve to reduce errors when building process environments. Refactor Centralized environment-to-dictionary conversion into the OS layer for consistent, safer environment handling across platforms.
