Tab warming was originally disabled in this test because it was accidentally
setting the DocShell to be active at an unexpected time.
Because tab warming no longer activates DocShells, we can revert this change,
though we also have to make it deal with the fact that switching tabs no longer
makes docShells become activate immediately.

There were a couple of things wrong here:
1 - The whole recursive frame load waiting thing was totally unnecessary. Load
doesn't fire on the window until all descendant iframes have loaded.
2 - The chrome event handler wasn't filtering by target, which it should. This
is probably to blame for the intermittent orange.
3 - Setting window.location during document load actually invokes
window.location.replace.
4 - Session history navigation seems to have weird behavior when called from
an onload handler. I wanted to investigate this further, but I've already spent
too much time on this. SimpleTest.executeSoon() seems to do the trick here.
