FWIW one of the original driver behind Eideticker (tuning Fennec for checkerboarding during scrolling) will become relevant again in the next couple of months as we transition Fennec to using the C++ APZ code and off the old Java pan/zoom code. While it would be nice to have Eideticker around to give us data on performance characteristics during this transition, I'm not sure if it would be worth the effort to get it up and running again.
