Extend lock error for not owned special case
Using the locking routines, it is useful to be able to
distingush a generic lock error from a one that is related
to the lock not being owned anymore (without doing string
checks); this allows say a lock extension thread to attempt
to re-acquire the lock in this case (vs just dying).
