rob just played with it for a while and got it to break.
of course, the current code doesn't behave exactly as acme's
anyway, and it should.

that's why i think it can be made to work.  i see the same thing.

surprisingly this is easier in x than in plan 9.
the bad part about sharing the snarf buffer with x is that
if you're running sam -r over a long-distance connection,
then if you snarf some big piece just to paste in another
sam buffer, there's no reason to pull it all the way across
the connection just to send it back up.  x's snarf model
accomodates this, though that makes it much harder to
deal with in the easy cases.

i'm sure scrolling during select is doable and fine.
"simple Athena/XTerm" was the scary part.
