I tracked down the problem (with near certainty) to the new shared mutex features in boost. Threads were waiting on each other for no apparent reason. Possibly incorrect usage of the mutex, or some kind of bug, I did not have time to dig deeper. Now using good old mutexes, plz reopen if the problem reappears.
