I applied your patch to CVS sources from 2007-01-19 and with it I
cannot reproduce the severe incremental undrawing I reported (see
http://permalink.gmane.org/gmane.emacs.devel/63681).  In my build from
those sources without the patch, I still get the bug.  Moreover, with
the patch I haven't observed the mild form I mentioned (I don't have a
precise recipe for reproducing that, but just experimented with
patched and unpatched Emacsen from otherwise identical source code).
So this fix seems to DTRT on this point.  (The patch does not fix the
second problem I mentioned: "Now click the MIME part header again to
close it, and either the entire header or the second line of will be
double.  Further clicking to open and close the MIME part increases
the number of (parts of) headers displayed.")
