The current browser competitive landscape is such that a 2% difference 
in benchmark times ends up exaggerated completely out of proportion by 
the marketing and the "journalists" that so love to republish press 
releases.

Even an efficient implementation of threading will give you more ovehead

They're probably ignore the spec, just like other specs that don't have 
buy-in from the people they're supposed to be binding on have been 
ignored in the past....
