    Oh, that's just the silly threaded test-binary. I don't know what you
    called it.

    As to your config options, yesh, you have some expensive stuff.
    DEBUG_OBJECTS and DEBUG_MUTEXES in particular tend to cause lots of
    horrible performance issues. I didn't check if there might be other
    things..
