Pkg exim4 users - Mar 2005 - incoming and outgoing use the same process?!

Krap! I have 20 messages to send during a 10 minute modem connection,
but I can only send about half of them because incoming (fetchmail)
and outgoing messages use the same process?!
# perl -wne ''s/\S+ ([0-9:]+) .* R=(\S+) .*/$1
$2/&&print'' /var/log/exim4/mainlog
04:35:39 procmail
04:35:47 smarthost
04:35:59 smarthost
04:36:08 procmail
04:36:41 procmail
04:36:49 procmail
04:37:07 procmail...
04:40:16 procmail
04:40:22 procmail
04:40:31 procmail
04:40:39 smarthost
04:40:42 procmail
04:41:44 procmail
04:43:15 smarthost
04:43:34 smarthost
04:43:40 smarthost
04:43:50 smarthost
04:43:59 smarthost
04:44:08 smarthost

No, it''s not a problem that they use the same phone line. There is
still enough capacity.  Also at the rate the smarthost processes them,
I could still get them all sent.  The problem is with 20 mails to
fetch and 20 mails to send, I ought to have separate exim4 processes, no?
