    Stop spilling tracebacks during normal operation

    Yes, they are innocent; yes, we log them with DEBUG level. But they
    scare people, they make people judge the software, they are bad PR, and
    they are probably redundant, string representation of the exception
    should be enough. If there is an issue that will result in retry
    attempts used without remedy, only then we should spill tracebacks and
    scare users.
