quote:  =E2=80=9CThe current windowing/graphics setup with /dev/draw as a ke=
rnel device and rio itself was implemented after Thompson, Ritchie, and Pike=
 left Bell Labs and others thought the window system needed optimizing.=E2=80=
=9D

This is not my memory.

work on plan9 switched to Brazil in 95, i believe it was seen as an experime=
ntal branch to try some major changes. the switch from 81/2 to rio and the n=
ew /dev/draw model was a major part of this. This was back ported to plan9 i=
n time for the 3rd release in 2000 - just around the time many left the labs=
.

I am not saying rio cannot be improved, but characterising it as inferior wo=
rk by inferior people is (i feel) unfair and incorrect.
