Case pthread_cond_broadcast/1-2.c trys to create as many threads and processes as possible which will wait on a condition variable.
Unfortunately,if some thread or child process waits overtime(180s) since maybe memory is not enough or whatever, it will call FAILED() and exit without unlocking a global mutex. Above-mentioned matter leads to a deadlock when parent process trys to pthread_mutex_lock the global mutex,and obviously status FAILED cannot be reahed by parent process. This patch fixes the deadlock problem.
