      Description

      We've hit an issue with spontaneous mongos deadlocks. Unfortunately I can't provide any hints for reproducing it but I've managed to take a core dump from troubled mongos process. See attached file with stacktraces from the core dump.
      It looks like all threads are waiting for ThreadPoolTaskExecutor to release _mutex which is acquired by waitForEvent method waiting for some event.
