Yes, but really I would rather have packages stored in separate
workspaces that the garabage collector avoided. Then space is less of
an issue. Ross I know suggested that, but I don't think anyone
is working on it.
My guess would be that we will not have any space/gc improvements
ready for 1.1, unless Luke's things are close. (BTW, Luke, is your
changed code available? I went to think about doing some timings the
other night and realized that I thought not. A cvs branch might be good(ish)
way to let us play with it.)
