Yes, I'll wait a bit until I see if I can reproduce it reliably.

well, it runs enough like a pig that although I'm able to move my mouse
cursor, X 4.3's mouse animation stops, and X itself stops handling focus
changes and all input until the "now closing down" window goes away.

I will henceforth run evo this way.  =:)  I'll also log everything to a
file so that if it does happen, hopefully something useful will show up.

well, again, when this happens, I can't do squat.  Even though I start
evolution with "nice evolution", I can't even switch to a VC until evo's
done with its thing.

well, I just checked the sizes on these and since I keep my Maildir
outside of $HOME/evolution, the only $HOME/evolution/**/*.ibex* files
that I can see are tiny.  

However, what you said makes perfect sense.  Like I said, my hard drive
goes absolutely bonkers when this happens, and from what I've seen in
the past (when copying large files/moving files/removing files, etc.)
with XFS, it seems that XFS takes up massive amounts of CPU to do
massive amounts of disk work--to the point that the system becomes
unusable until it's done.  Now, this was a while ago and I'm hoping that
XFS 1.2 has improved, but it just seems like this could be pointing to
XFS in some way (as a side-result of some fonky evo behavior).

Now, there's a couple of things that I can think of, given the above,
that might lend itself to this lock-up.  I normally don't "auto-expunge
trash on exit" with my $HOME/Maildir, which means, that I may have more
than several hundred entries in that vfolder at any given point in
time.  It would seem that this might be problematic.  What do you think?

Also, I currently have bogofilter/procmail sending spam into a
$HOME/Maildir/Spam Maildir, and though evolution doesn't see this
automatically get updated when procmail puts mail there (while evo is
running), I'm wondering if it realizes that there's a whole bunch of
mail there since last time it looked (when it's going to shut down) and
tries to deal with them there?  Like maybe it's updating the default,
un-deletable "Unmatched" VFolder, since the Spam Maildir is inside the
top-level Maildir that evo knows about?

Thanks for the reply, notzed.  =:)
