It's too bad that it's sent as a signal...  I don't know how to handle
that race condition.  Is there some other signal that would signify that
we're NOT going to receive one,?  Or can we "solve" the race by making an
assumption that the signal would arrive within some (short) period of
time?

I guess this is a bad assumption by Apple that apps default the opening
empty.
