And when I do the same thing on the mail server for python.org (which
hosts over 100 lists, including some pretty active lists with large
numbers of subscribers), on the largest queue runner we have
(ArchRunner at 41m), I see:
# pmap 1040 | sort -nr -k 2 | head
total 45800K

No heap showing up anywhere. Doing the same for our IncomingRunner, I get:
# pmap 1043 | sort -nr -k 2 | head
total 23144K

Again, no heap.
None of the lists seem too big:

Where did you do this? In the /usr/local/mailman directory?
When I did this in /usr/local/mailman, all of the .pck files that
showed up were actually held messages in the data/ directory, not in
lists/. This would mean that they were individual messages that had
been pickled and then held for moderation, not pickles for lists.
Doing the same in /usr/local/mailman/lists, I find that one of our
smaller mailing lists (python-help, seventeen recipients) has the
largest list pickle (1044 kilobytes). We have a total of 150 lists,
and here's the current subscription count of the five biggest lists:
4075 Python-list
3305 Tutor
2600 Mailman-Users
2329 Mailman-announce
1528 Python-announce-list
Of these, python-list and tutor frequently gets between twenty to a
hundred or more messages in a day. However, here's their respective
list.pck files, using the same "du -sk" script from above:
904 tutor/config.pck
652 python-list/config.pck
476 mailman-users/config.pck
324 mailman-announce/config.pck
208 python-announce-list/config.pck
