Now that I think about this, this is probably a major problem with
using ifile and imap together: one of the main points using imap is
not downloading the entire message before you really want it.  I'll
bet gnus only downloads the headers for splitting.  To use client-side
ifile, gnus will have to download entire messages (or at least all the
text parts), which will probably have significant performance impact
when you're on a slow connection.  When I surface for air in a week or
two, I'll maybe look into implementing this as an option, and see how
much people grouse about performance impact.

PS For IMAP, server-side ifile-splitting would really be the right
   thing.  That is beyond the scope of my current mail-hacking
   ambitions.
