[9fans] drawterm's #i

[Skip Tavakkolian]

On a term when I cpu over and check '/dev/draw' I see the actual
windows. With drawterm, each window seems to get a new copy
of '/dev/draw' namespace. More accurately you can some of the windows
(winwatch, page -w, stats, etc.) but not windows running rc.  Why
is that?  Thanks

Running 5 drawterms is like sitting at 5 different physical terminals.
In both cases you can't see stuff about one terminal when sitting at
another.

What I see (all in one drawterm session) is this. I 'New' a window and then:

"window" interacts with an instance of rio mounted on /mnt/wsys.
/dev/draw happens to be used by rio.  If you run drawterm but don't
start rio, "window" has no one to talk to.
