Subject: [PATCH] Suppress Thread Sanitizer for ThreadPoolProc

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.
