is there any reason one couldn't send a "stop" message to
a rio window just as an "interrupt" message is sent currently?

there's no essential reason why you couldn't do that under plan 9,
i think. just put a level of indirection above the draw device.

i used to like that feature of "screen" - i could keep several programs
going in one session and remain logged in for days despite
logging in from several different terminal rooms.

acme dump is ok, but has certain lacks.

i think rob's got some ideas on this...
