*
* Test Synopsis: Test asynchronous cancelation (alertable or non-alertable).
*
* Test Method (Validation or Falsification):
* -
*
* Requirements Tested:
* - Async cancel if thread is not blocked (i.e. voluntarily resumes if blocked).
*
* Features Tested:
* -
*
* Cases Tested:
* -
*
* Description:
* -
*
* Environment:
* -
*
* Input:
* - None.
*
* Output:
* - File name, Line number, and failed expression on failure.
* - No output on success.
*
* Assumptions:
* - have working pthread_create, pthread_self, pthread_mutex_lock/unlock
* pthread_testcancel, pthread_cancel, pthread_join.
* - quserex.dll and alertdrv.sys are not available.
*
* Pass Criteria:
* - Process returns zero exit status.
*
* Fail Criteria:
* - Process returns non-zero exit status.
