Remove WebKit animation bugfix
This was fixed both in Safari (5.1) and Chrome (13)
Also, as mentioned here and in this tweet, it might cause excessive CPU usage
FAIR WARNING: Readers Adam Ferguson and Simon Goellner both wrote in to tell me this fix was the direct cause of some heavy CPU consumption on sites they were working on.
this is making the otherwise static site use a moderate amount of CPU on my computer :(
