Ideally you would make a copy in memory, ship it down the delivery
pipeline, then work on the next copy... really only need a few copies
actually in python memory at once (pretty much just the number of
outgoing delivery streams).

Fun :-)

Of course as the MTA catches these its going to make a queue file on
disk for each one unless you can do this funky passing the VERP stuff
down the pipeline stuff thats been mentioned on the list before.
