Yeah, but if Gmane receives 1000 messages over a 30-second period,
then the machine will have run out of processes, and messages will
start to bounce.  Unless there's something in exim to control how
many local delivery agents are running at the same time.

I've just had a quick look over the package, and it seems to use a
quite different methodology.  If I read it correctly, it goes through
all the To and Cc addresses, and compares that to the list of
subscribed mailing lists.  And then it uses that to find out which
groups to (cross-)post the messages to.  Which might work quite
well -- at least for cross-post handling.

Yeah.  :-)

Well, I could delay feeding other servers messages until, say, 10
minutes have passed, and then things should be stabilized on
