New Revision: 64570

Log:
Give information for compililation of _multiprocessing.SemLock on FreeBSD:

FreeBSD's P1003.1b semaphore support is highly experimental and
it's disabled by default.  Even if a user loads the experimental
kernel module manually, _multiprocessing doesn't work correctly due
to several known incompatibilities around sem_unlink and sem_getvalue,
yet.
