SVN rev 189781 on 2009-03-14 01:12:35Z by bms
MFC rev: 189736
Ensure that the semaphore value is re-checked after sem_lock
is re-acquired, after the condition variable is signalled.
Early MFC, as the test case in the PR is fairly complete and the
submitter also re-ran test case on -STABLE. It also bites Python
fairly hard, which will otherwise try to use POSIX sems for its
internal thread synchronization; this needs more in-depth testing.
