This should be possible. In fact, provided one has a decent library used by the
applications on the client side, one should be able to save and restore
THE WHOLE DESKTOP like in Smalltalk.

GNU Emacs has some nice code that it uses for loading faster. It will load the
ELISP code into its data segment and then produce a core dump of itself. Then
this core dump is converted into a new executable which has all the ELISP
stuff preloaded (minus user ELISP files, of course, I'm only talking about
the basic editor code here). If one could also save info about the call
chain, a RESUME would be in reach. We have the problem with limbo descriptors
of course, but that's what the "decent library" is all about.... I expect
the library would also have to talk to NeWS to save/restore what ever the
client had going over there. If the client only goes trough The Nice Library
for doing graphics (farewell, extensibility ;->), the graphics wouldn't
be a problem either.

systems ;-)]
