The call to do_oop will (potentially) only change oops already stored in the lock stack, not add or remove anything. If two (or more) oops were equal before doing do_oop on all oops, they will still be the equivalent after the operation. Hence, the consistensy check only needs to happen once, either before or after do_oops, and doing it before might crash, so I propose we remove it.
