    queue2: do not post buffering messages holding the lock

    It might cause deadlocks to post messages while holding the queue2
    lock. To avoid this a new boolean flag is set whenever a new
    buffering percent is found. The message is posted after the lock
    is released.

    To make sure the buffering messages are posted in the right order, messages
    are posted holding another lock. This prevents 2 threads trying to post
    messages at the same time.
