Hello!
When fixing JDK-8069048 a potential race was overlooked:
1) Thread A wants to call _endthreadex() and registers itself,
2) Thread B wants to call exit(), takes its turn and raises the flag
`process_exiting`,
3) Thread A continues, and gets captured in the loop at 4020, in
SuspendThread(GetCurrentThread()),
4) Now, the thread B will have to wait for all the registered threads,
including the thread A, which will never wake up.
Would you please help review the fix?
