  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.
