I get 75% CPU utilization at this point. But perhaps I have a faster graphics
sub-system (a slower one could pause the renderer for longer).

This is a very good point. When I turned the status bar off, CPU use went up
to 100% on the same scene during the photon build stage. On the whole it didn't
make a huge difference (see below) but it could do so on slower machines. I'll
make some sort of work-around for it.
