First-class Continuations would of course trivialize threads,
as well as being of great help to support the Schemists among LispOSers.
If you fear about the power of duplicating continuations,
you might require that they only be used in linear context,
but I'm not convinced you gain much at that.
What about MIT-Scheme instead?
Or RScheme? RScheme already has a persistent store and real-time GC!

ACL is not quite free, so we can't hack it into an OS.
Btw, anyone managed to get it running?
it keeps dying during initialization, to me --
Franz tells me to reinstall Linux )-8 .

If we're going to strip something, Linux may not be the best idea.
We'd better go with HURD, BSD, VSTa, or something finer-grained.
Also, there's a lot to recycle from the Fox project at CMU --
the only OS I know (besides the dead OSes of LispMs)
written as a set of modules and functors
in a higher-order functional language.

Well, there already exist window systems for CL,
and a lots of non-standardized things in Scheme,
all running on top of X.
In a first time, we could just use a linux-based X server;
for direct hardware support, we could move with something purely LISP
by recycling code from DDX and GGI.

I have gathered a few ideas for user interfaces in
Of course, in a first time, we could use edwin, emacs,
or whatever free Lisp interface exists at the time...
