 detection, since the code has to chase down the owners of locks that may
 be entirely unrelated to the one on which the lock is being acquired.

+For deadlock detection however, the blocked_hash_lock is also held. The
 fact that these locks are held ensures that the file_locks do not
 disappear out from under you while doing the comparison or generating an
 owner key.
