Summary:                    POSIX thread operations errors
Description: 
POSIX thread functions pthread_cancel, pthread_kill and pthread_join are
called with thread IDs belonging to monitor threads that (may) have ended.

---------------------------------------------------------------------- 
The specific code defect is that POSIX thread operations are done on
threads after the detached thread has been cancelled, or in the unlikely
case of hardware, compiler or operating system failure, abnormally ended.
After a detached thread has ended, the dynamic memory allocated to it can
be freed. Therefore, memory faults can occur. Cancelling a thread allows
its dynamic memory to be freed.
