With this diff applied, Youtube videos (fullscreen and otherwise) work
nearly perfectly for me, in Seamonkey and Chromium, on an eight-year-old
Thinkpad T60p. CPU is a Core 2 Duo T7600@2.33ghz. Without the patch, it
wasn't remotely usable in either browser. top(1) shows chrome at roughly
20% CPU use, and seamonkey at 40%. Anecdotally, Youtube works better
than it does on Linux, for this machine.
