    pad: don't call pad block callbacks multiple times

    Ensure that when multiple threads try to block a pad, only one of the
threads
    calls the callback. We do this by checking if the callback was already
called.
    The previous version unconditionally called the callback and then checked
if it
    was already called...
    Also only call the unblock callback once from the first thread that
unblocks.
