I would think it would work fine with unexec (except that you would get a lot of "unknown resource" errors from X if you try to access a frame that is no longer there). I suppose you could get crashes from resources that weren't properly finalized. I don't think good support for unexec across the board is in the cards, though.

I don't think this has much advantage over redumping from scratch, except saving a couple of megabytes of disk space per instance on single user systems. AFAIK even with pdump you need to dump with the same temacs you are going to reload into, so if you tried to have a system xemacs and per user dumpfiles, you'd still force the users to redump on every system update. -- School of Systems and Information Engineering http://turnbull.sk.tsukuba.ac.jp University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Ask not how you can "do" free software business; ask what your business can "do for" free software.
