Mailman's CalcrRecips module loops through all the member addresses in a list comprehension, but all other information is requested a member at a time.
Note that if it was too expensive for getRegularMemberKeys() to return an in-memory list, it could (if you use Python 2.2) return an iterator object that implemented things in a more efficient manner, e.g. by paging through blocks. I believe that any place where we expect a Python sequence (list) we could probably accept an iterator.
