A 7%-28% hit? Yeah, not so much. Thanks for checking!

Do you have a shortcut to working out which x11perf tests are going to
hit a particular code path? I'd have been happy to test this myself if
I'd had any idea which tests would be reasonable. Running all of
x11perf is too painful for a quick "I wonder if...?"
