Back out part of previous commit (even though it's technically correct).
Our spinlock implementation allows a particular thread to obtain a lock
multiple times, but release the lock with a single unlock call.  Since
we're detecting recursion, we know the lock is already owned by the
current thread in a previous call and must not be released in the
current call.  This is really far too dependent on this particular
spinlock implementation, so I've added commented out calls to
THREAD_UNLOCK in the appropriate places.  We can activate this code when
spinlock is taught to count each lock operation.
