Thread Sanitizer reports data races on PoolHalting in THREAD, shared between ThreadPoolProc and WaitThread. But if WaitThread reads false, synchronization is ensured by Wait from the PoolWaitList. If it reads true, WaitThread simply returns.

## Manual PTHREAD_MUTEX_RECURSIVE
|
|
# The Lock/Unlock mechanism on Unix is a manual, hand-coded implementation of PTHREAD_MUTEX_RECURSIVE.
|
|
# We avoid using the PTHREAD_MUTEX_RECURSIVE directly because it exhibits critical bugs, such as deadlocks
|
|
# on certain older systems(Linux, Solaris, or macOS). While Thread Sanitizer will report data races,
|
|
# these warnings should be ignored as the logic has been carefully implemented to ensure thread safety.
