There is currently a bug in bugzilla about this as well:
http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=22369
(submitted last week)
I'm currently testing flyspell-buffer on /usr/share/dict/words (0.5
MB) - it's now been probably 10 minutes or so, and it has finished
35%. Aspell has also grown to about 45 MB, so I'm pretty sure there is
a memory leak there.
