pthread_create leaves valid mutex pointers on the stack

Cygwin's pthread_create function leaves a pointer to the pthread object's mutex member on the stack. If you subsequently call pthread_mutex_init on mutex in an automatic variable, it's possible for it to reuse this stack slot. In this case, pthread_mutex_init observes that the mutex object is a p
