Er, webkit-patch doesn't seem to have an option to add a description, unless I confused it with the title.  Sorry if I missed something.

I plan to use USE(CHROMIUM_NET) to unthrottle some preloading, like so:

 }

Let me know if I should add this change into the proposed patch.  I wasn't sure if they should be separate or not.

Why do we need another flag as opposed to just using PLATFORM(CHROMIUM)? It feels like another flag is only needed if you would choose CHROMIUM_NET independently from PLATFORM(CHROMIUM).

I am ill-equipped to justify this, due to my lack of WebKit knowledge.  I asked abarth how to implement my change for preload scanning and he suggested a USE macro.  If PLATFORM is the way to go, I'm happy to use that instead.  I will note that the Android browser (which I believe is the Android port in the webkit tree, although I'm not totally sure) uses the Chromium network stack.  So if it doesn't/shouldn't use PLATFORM(CHROMIUM), then perhaps USE is more appropriate here.  But I don't particularly care.

Cool, great.
