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.
