Weird.  I used the built-in zipper in ubuntu.  But since cvs now
magically works for me again, this has become obsolete fortunately.

Yep, I think we never had cells3 be part of cells-gtk3 (I guess part
of why we did cells-gtk3 is so that we don't have to include out own
fork of cells anymore).

BTW, do you have strong feelings about how to structure the cells-gtk
tree?  you had flattened it in cvs, I had it restructured to match the
old cells-gtk (so I could merge in my patches).  Which one do you
prefer if any?  If you don't care either way I will try and
restructure cvs to match the old cells-gtk tree structure for the sake
of consistency.

Gotta love (+ lisp cells).  test-gtk has had that feature for a while,
I think (at least longer than I have been on board).  I remeber it
took me a while to understand what was *really* going on when I saw it
first.

Cooperative scheduling, heh?  Apparently cells-gtk on
Lispworks/Windows has similar issues (there's a work around somewhere
in cells-gtk).  So far I haven't seen that with sbcl/linux.  Maybe
threading works better over here, maybe gtk does a better job of
keeping the load in the main loop know.

Those issues aside, doing repl stuff while having a gui up is really
neat, isn't it?

Well, I'd love to have these things up and running in my thesis talk
two months from now, so it won't hurt to be a little ahead of
schedule.

Wow, sounds like a great program.  It seems next time they could save
the trouble of inviting other speakers, and just let you talk for the
whole two days. :-)

Anyway, good luck with all of it, and I am looking forward to watching
the recording.

Cheers,
