    pthreadpool: Signal job completion without the pool mutex
    This essentially reverts 1c4284c7395f23. We now call an alien function from
    within pthreadpool, and we should not hold a mutex during that call. The alien
    function could (and pthreadpool_tevent_job_signal actually does) lock a mutex.
    We can't guarantee proper lock ordering here, so in theory we could deadlock. I
    haven't seen it in the wild yet, but I could imagine that both _parent pieces
    in pthreadpool and tevent could trigger such a deadlock.
