I should add that I understand your previous objection that creating
framebuffers on the fly is not performant enough, and you object to
the effort of managing 100 rather than 50 framebuffers upfront (though
honestly, if you get to 50 framebuffers you're already having to do
some clever setup/management anyway). But in the last thread, Daniel
Vetter asked for some performance numbers to bear out your objection
that framebuffer creation is too costly, leading to getting it fixed
if this is in fact the case (since other userspace relies on it being
fast), but this performance analysis never arrived.

I'd still be interested in seeing that.
