I'd like to see *use-dedicated-output-stream* supported: It is useful
and sometimes necessary for output to not to go through the whole of
slime repl's infrasturcture.

| To fix that, we would need to synchronize the two streams. That's not

There was a SERVE-TIMER conribution in 2004 posted in
I was using this for a while, and hoped it would be included into CMUCL.
I'm not sure how to reach the author now. Perhaps it could still be
added to CMUCL?
[For my own stuff, since then, I've been task queues running on top of
MP to implement timers. I'm not sure if this is better than serve-timer
for a general CMUCL solution for inclusion in CMUCL. For an early
prototype implementation of teh PQ based timer, you can search google
for "cmucl"+"cron.lisp" and skip any bknr links. I'd be interested in
advice on both]
