I haven't forgotten about this patch, but I found a nasty corner case in
GAtServer that breaks the current implementation.  I'm still looking for
a nice solution.

Can you brainstorm some ideas of a way not to use a g_timeout_add and do
the finish notify synchronously?  I suspect there is a nice(r) solution.

I pushed my own version of this patch.  I have performed basic testing
here on my end and it seems to be working out quite nicely.  However, I
have not tested the HFP emulator proper, so could you please double
check my logic and make sure that I haven't done anything silly?

Thanks,
