I have been performing further experiments on this question (reading
my RMAIL file into latest CVS emacs). On a 2GHz AMD64x2 machine it
took 118minutes of CPU, basically 100% of one processor for 2 hours to
obey M-x rmail-mode after I had loaded the file with M-x
find-file-literally. This seems in line with my belief that the
algorithm being used is n^2, and for my 95Kb file is totally
unacceptable . . .

I cannot reproduce this on my 1.8GHz i686 Athlon with 256M of RAM, using
emacsen built from trunk today and on 27-Jan (i.e. both before and after
the Unicode merge). I observe linear CPU-time growth between files of
127M and 254M (albeit artificially constructed ones), to a total of
about 18sec and 34sec respectively.
I wonder, how much RAM do you have on this system?
