I wanted to avoid that so LOCKDEBUG was not so slow. There again, LOCKDEBUG
doesn't really need to be quick. It only needs to _not_ make the machine
unusable.

I think this is a good idea. lockdebug_lookup() could do with a different
method of hashing that takes the lower order bits into consideration - I'll
investigate that.
