I think it should be applied now. I've briefly looked at Jeff's patch
and I don't see any problems looming there.

Jeff performed tests with Simon's original patch and his patch, and I
think the results from those tests are still valid since the basic
behavior hasn't been changed. I'll repeat those tests myself, and run
some more to see if the added CPU overhead shows up in tests, but I'm
pretty confident the patches will work together as advertised.
