One way to figure this out is to 
	1)  Increase your swap space so you don't get the out-of-swap errors
(you absolutely MUST do at least this if you want to avoid the mailman
problems)
	2)  Watch over your system when the list posts are sent.  The "free"
command, and similar information shown by "top," will show how much RAM
and swap space is being used (in Linux at least)
	3)  Increase your physical RAM to at least the amount of swap space
that was being used.  The object is to never have to use swap, but have
it available for "emergencies."

If you're using Linux, and I think other OSes do this too, be aware of
the buffers and cached stuff that shows in the output of "free".  The
memory that's actually being used by programs is in the "-/+
buffers/cache" line.  The buffers and cache speed up performance in
certain ways, but the kernel will automatically reduce their use when 
memory is allocated by actual programs.
