Yep, should have started with that one. I've several clients that
are working with the same black board. There's one master (the first
launching process), and N clients. When setting a variable in the
BB through the master, the clients are supposed to be notified that
something is happening. In that case a bb_snd_msg() is called with mtype
being the PIDs of the clients[1].

Hence the problem: if one of them dies unexpectedly, we fill the queue,
and we don't even know that. So no one gets notified anymore.

BTW, this is all RMS compliant, as the code is GPLed and in the CVS under
the dadi module (well, not that msg part exactly, as I'm working on it :)).
I'll write a blurb on it as soon as it is a bit more polished.

[1] The PIDs are known because an REGISTER msg is sent after a client
successfully attaches to the BB
