Summary: Runs out of memory on larger (5M) messages.

Initial Comment:
When trying to send an email with a 5M attachment,
Mailman seems to run out of memory.  On the console I get:

marcos:mailman {106} Traceback (most recent call last):
  File "/usr/local/mailman/bin/qrunner", line 270, in ?
    main()
  File "/usr/local/mailman/bin/qrunner", line 230, in main
    qrunner.run()
  File "/usr/local/mailman/Mailman/Queue/Runner.py",
line 59, in run
    filecnt = self._oneloop()
  File "/usr/local/mailman/Mailman/Queue/Runner.py",
line 111, in _oneloop
    self._shunt.enqueue(msg, msgdata)
  File
"/usr/local/mailman/Mailman/Queue/Switchboard.py", line
91, in enqueue
    msgsave = cPickle.dumps(_msg, 1)
MemoryError: out of memory


The system is: OpenBSD 3.1, with 512M ram. Mailman
version 2.1.1

It would be nice to be able to have large attachments
as I want to use this for my company's support email
which quite often has larger than 10M files attached.

Thanks,
-- Steve
