OK, I can make it so. While I still think this is a bad choise, because
the key difference is the locking, where the rule of thumb is never spread
locks over different functions, they must be released in the same function
they have been taken (with rare exceptions). But I won't insist. If you
and Serge are agree I'll rework.
