I wish I could isolate a repeatable case.  For me, the times I see it
are times like coming out a screensaver, or bringing the window up
from under firefox.  But it's not always related to redrawing the
screen.  I also sometimes see it when I do things like click on a
mail messsage to view it.  If there's anything consistent, it seems
to be triggered by X activity rather than CPU activity, but that's
a general impression without supporting data.  The fact that I
usually have upas/fs running means that network activity could
well be connected.

Cheating or not, I've found it to be one of the most interesting
and useful things I've come across in years.  So thanks again for
it.
