open_posix_testsuite: fix pthread_cond_destroy test error. #1097

Open qinyuntan opened 7 months ago

qinyuntan commented 7 months ago

According to the description of the pthread_cond_destroy function in glibc 2.32, it is advised to ensure that all threads blocked on the condition variable have been successfully awakened before calling this function, otherwise unpredictable situations may occur.

In the glibc 2.32 version, this testcase will hang. Therefore, it is necessary to ensure that all threads have been successfully awakened before calling pthread_cond_destroy to destroy the condition variable.
