Okay, I'm typing this in pine, running in a gnome-terminal window, and I see
a solid improvement in responsiveness.  Definitely useable again, even if not
ideal.  There is still some hesitation while echoing chars to the screen,
but much improved, thanks!

BTW,  I think pine has little or nothing to do with this -- since I get the
same lag when just typing chars into the gnome-terminal command line.

I never mentioned before (but I'm sure you already know) than running the
'buildworld' in an xterm window was always light-years better than running
it in a gnome-terminal window.

I've noticed that gnome-terminal allows you to click on any URL that is
printed out in a gnome-terminal window -- so it must be parsing in real-time
all of the text that passes thru its rather clumsy hands.  I'm not at all
sure that this is a valuable feature -- I'd vote for its removal.

However, gnome-terminal's prinicpal asset is that it is a great benchmark
for scheduler maintainers ;o)
