When starting applets I see this spewage in Console.app:

6/19/12 12:30:04.288 PM [0x0-0x451451].com.apple.Safari: Browser supports CoreAnimation rendering: 1
6/19/12 12:30:04.288 PM [0x0-0x451451].com.apple.Safari: Using CoreAnimation rendering model
6/19/12 12:30:04.288 PM [0x0-0x451451].com.apple.Safari: supports Cocoa event model: 1

If it's us (as opposed to Safari itself) who is printing it out, we should clean it up and remove it.
