Gregory P. Smith 68e0135e41 Fix multiprocessing Semaphore's on netbsd5. SEM_VALUE_MAX is defined 
as (~0U) on NetBSD which was causing it to appear as -1 when used as
a signed int for _multprocessing.SemLock.SEM_VALUE_MAX.  This works
around the problem by substituting INT_MAX on systems where it appears
negative when used as an int.
