For what it's worth, if someone can point me to a script they actually 
want such measurements for, I'd be happy to produce at least Gecko 
numbers for how long the various parts take.  While the different parts 
of the pipeline are not separable from the point of view of a web page 
right now, Gecko internals and profilers have no such limitations.

That's assuming people actually want numbers here.
