I said that this should work, but turns out that Firefox has the same behavior
in this respect. The attached test case doesn't fail there for a different
reason, but if you move test execution into an onload handler, then
subresources won't be revalidated. It's just timing of when requests are
started that makes the behavior look different.

So, both Safari and Firefox forget that the document was a reload once load
completes, and any resources that are added dynamically later aren't
revalidated (unless they have appropriate Cache-Control headers, of course).

A workaround is to use Empty Caches command from Safari menu. I've changed bug
summary to reflect that there is a workaround that doesn't involve restarting
Safari.
