This is something I've thought about. It would interesting to have an 
option similar to the db pooling to keep alive the V8 engine + compiled 
script for fcgi. I don't think it will be done in this phase but 
certainly in the near future.

Styles are touched. First time: JS Engine Initialization + script 
compilation. Then only execution.

No plan for url at the moment. Could be a good addition in the future 
though and should only be an internal change.
