Have we really looked into this?  I feel like we're all just throwing
our hands up in horror without seeing if there is anything we can do.

I looked at this very briefly, and discovered that the uxa / fallback
mode seem to be interacting in a pretty atrocious way; a way that seems
worse than I would expect.

For example, doing very simple operations (opening an xterm, typing,
etc), results in whole screen draws.  Every time.  Surely we can look at
the code path and figure out why that's happening, can't we?

Has anyone asked Adam Jackson about this?

Cheers,

Jeremy
