Cygwin: posix timers: fix resource leak On setting the timer, the thread is accidentally only canceled when disarming the timer. This leaks one thread per timer_settimer call. Move the thread cancellation where it belongs. Signed-off-by: Corinna Vinschen <corinna@vinschen.de> 2019-03-06 22:17:32 +01:00			`What's new:`

Cygwin: posix timers: fix a deadlock Canceling the timer thread runs under lock. The thread uses the same lock to guard its timer_tracker struct access. If the timing is bad, timer_settime or timer_delete grab the lock at the same time, the timer expires. In the end, cancel waits for the thread sync while the thread waits for ther lock to be released. Fix this by not waiting for the thread sync under lock.
