If SBCL counts as CMUCL-related, I am presently engaged[*] in adding
thread support to SBCL.  These will be userland threads, but I can see
a few changes that I think will make them faster than the present
CMUCL implementation anyway.  Except for SMP I'm not sure what native
threads buys on a Lisp, given that (a) userland threads can be faster
anyway, and (b) all "normal" IO gets channeled through the library in
such a way that it can be made non-blocking.  In fact, in CMUCL and
SBCL it already is; this is how serve-event works.

I'm pretty sure this is not what Craig was thinking of, however, as I
only started it about a week ago.  More details on the sbcl-devel
list, or ask on irc (irc.openprojects.net, #lisp)


[*] For "engaged" read "hacking on my own time".  Open to offers, though.
