Thanks for all the testing, and thanks for the (now merged) patch, Pavel.

Actually, the CPU usage is not surprising; the screen scanning,
particularly for large displays, does not yet back off under periods of
light activity.

There is another issue I'm mentally chewing on, which is the way it
handles a 'worst case' - e.g. x11perf doing 1x1 draws over and over
again.  In the former case, we want to back off scanning and lean on
damage reports; in the latter case, we want to ignore damage reports and
just scan.

The other fairly substantive issue I mean to tackle yet is to provide
some form of caching for the shared memory segments (right now, it's
simplistic; just alloc, use, and free).  First I have to benchmark to
determine if they are inefficient, and if they are, then I think having
a reusable cache should provide a nice speed up as well.

I'm glad it's broadly usable; I hope to have a patch attacking the CPU
usage sometime fairly soon.

Cheers,

Jeremy
