This is an attempt to reduce areas that execute with mutex unlocked
because the called code may deadlock. Also, this copies objects on
stack before unlocking, using lambdas' own variables.
I hope that it somewhat improves reliability. OTOH, this runs more
code with lock active, has a potential of new deadlocks, so risky.
