I hope you're using apt-proxy so all those downloads are now mirrored
at your site in a form where they will automatically be used for the
next install.

You could change that.

Break down and write scripts.  Wrap both fetchmail and exim in scripts
which first use lockfiles to hold the connection up, and then when
they're done, use a conditional "poff-if" to tear it down if they're
the last user.  Scripts appended below are not what you need, but
might be useful for reference.

Use wwwoffle.  It's a debian package.

#!/bin/sh

# SYNOPSIS
#	pon-if <id>

# DESCRIPTION

#	Lock file /var/lock/modem-users.lock to gain exclusive access
#	to the /var/lock/modem-user-*.lock name-space.  Then if the
#	modem link is down, remove possible (stale) files in this
#	name-space and bring the modem up.  Then add <id> to the list
#	of current users of the modem by creating a file
#	/var/lock/modem-user-<id>.lock.  Finally, release the lock on
#	the /var/lock/modem-user-*.lock name-space.

#	Uses /var/lock/LCK..modem to test whether the modem link is
#	up.  (What's a better way?)

# SEE ALSO /usr/bin/poff-if

lockfile /var/lock/modem-users.lock

if [ ! -e /var/lock/LCK..modem ] ; then
    rm -f /var/lock/modem-user-*.lock
    /usr/sbin/pppd call provider
fi

touch /var/lock/modem-user-$1.lock

rm -f /var/lock/modem-users.lock

#!/bin/sh

# SYNOPSIS
#	poff-if <id>

# DESCRIPTION

#	Lock file /var/lock/modem-users.lock to gain exclusive access
#	to the /var/lock/modem-user-*.lock name-space.  Then delete
#	<id> from the list of current users of the modem by removing
#	any file /var/lock/modem-user-<id>.lock.  If this leaves no
#	remaining current users of the modem, take down the modem
#	link.  Finally, release the lock on the
#	/var/lock/modem-user-*.lock name-space.

# SEE ALSO /usr/bin/pon-if

lockfile /var/lock/modem-users.lock

rm -f /var/lock/modem-user-$1.lock
if [ -z "$(ls /var/lock/modem-user-*.lock 2>/dev/null)" ] ; then killall -q -w pppd ; fi

rm -f /var/lock/modem-users.lock
