While mailman routinely handles much larger lists (1), you seem to be very 
concerned about the size of a HTTP-based bulk add operation when there are 
other methods of adding that many recipients. Perhaps mailman does have a 
bug in the area, but there are many other potential factors that could slow 
things down or stop them completely (2).

It also sounds like there are other issues with the system, like postfix 
delivery times and the length of the CGI timeout.

If you're receiving "please stop" messages from users, maybe those users 
don't want to be on this list at all.

This all seems like making a mountain out of a molehill. If you've been 
satisfied with mailman, why not continue to be satisfied in all other areas 
and just not to large bulk adds via http? (My car is a great car but won't 
carry 500kg of cargo, so I don't ask it to.)




(2) is the mailman installed on local disk or an NFS share? what the locking 
scheme? timeouts? etc
