JS component fastload for ff2?

[Brian Ryner]

What do you guys think about taking JS component fastload on the 1.8 branch
for Firefox 2? This has been on the trunk for awhile (without any
regressions that I've heard about), is a very self-contained change, and is
a pretty sizable startup performance win for large JS components, like some
of the ones in the Safe Browsing extension.

Thanks!

By how much does it help improve the startup time of "bon echo" with
safe browsing enabled?

Also, we should consider that the search service and session restore are
additional large JS components that would likely benefit from this
patch. I think we want this, if not need this.

On trunk with sb enabled, I was seeing about a 14-15% regression using
the JS subscript loader. When I switched to using the preprocessor and
#including the files, I saw about a 3-4% regression.

I'm in favour. Good win, well-baked.

Yep - exactly the sort of thing we need, actually.
