  I was under the impression that a spinlock (from Posix threads/parallel
processing terminology) was a mutex which was locked by repeatedly trying
to grab the mutex for a short period of time (useful only on parallel
processing machines where grabbing a new processor outweighs the extra
CPU cycles expended on the old one).
