I have not been able to get sunspider or dromaeo to react beyond a noise level with this change. 

That being said, the change eliminates ~571 calls to Timer::startOneShot in a single sunspider run. The reason I'm not seeing results is because calls to setNextFireTime entries are coalesced when they are very close together.


So... I an argue either side on this one. I like that it is eliminating scheduled timer callbacks (overhead in general), but in the existing benchmarks I'm not able to prove it makes a huge difference.
