Hmmm.  In my FreeBSD port, I implemented the GLOCK with a mutex.  You
can't sleep while holding a mutex, so it gets automatically dropped by
the OSI sleep/delay code.  (I've never tested this particular code
path and plan to replace it -- in my CFT -- so I don't know whether
this is actually safe to do in this case.)
