Okay, I give up: what (or who) is `buffer-swapped-with', and how is it
related to this issue?

As for an alternative for fixing this, if the current kludgey way of
using annotations for switching to the right buffer behind
save-buffer's back is acceptable, we could add to
rmail-write-region-annotate another hack: a call to buffer-size
followed by the same message "Saving file ..." that should have been
displayed by save-buffer.
