How very odd.  I have the same setup, but with a real IMAP server, and
not nnimap-shell-program, but that shouldn't make a difference.

I've stared at the code some more, but I can't find out why the
expirable marks go missing.

Would it be possible for you to edebug through parts of
gnus-summary-exit to see when the expirable marks disappear?
