When ever the list is updated, the process creates a new, temporary
file, and only after successfully updating that file does it rename it
to config.pck. Thus, every time a list is updated in any way, the
owner of config.pck becomes the owner of the process that did the
update, in this case, the qrunners.

There is something wrong in your installation. Either the CGI wrappers
(the files in Mailman's cgi-bin directory) are not group mailman and
SETGID, or your web server/OS is not honoring the SETGID bit and
setting the effective group of the CGI process to mailman.

In short, the owner of config.pck shouldn't matter because access is
supposed to be by group.
