Log:
SVN rev 180032 on 2008-06-26 13:51:25Z by jhb
Change SEM_VALUE_MAX (maximum value of a POSIX semaphore) from UINT_MAX
to INT_MAX. Otherwise, a process could create a semaphore (or increase
its value via ksem_post()) beyond INT_MAX and sem_getvalue() would return
a negative value. sem_getvalue() is only supposed to return a negative
value if that is the number of waiters for that semaphore.
