While profiling bug 857359, I'm finding that the nsHtml5TreeOpExecuter hogs a lot of main loop time. Of that, most of it seems to be consumed by preloading images. I narrowed it down to imgLoader::LoadImage(), but I'm not sure what's taking so much time there.

Could this move to some other thread than the main thread?

Not sure. imgLoader::LoadImage() does some stuff with a cache (simple hashtable), but mostly seems to just to open a channel.

These profiles would be more useful with stack walking, and symbolication.

You can see in this profile that much of the time is spent notifying HTTP observers when the request begins. Looks like this is a dup of bug 1148544.
