I think this is more of a docshell issue.. but I could be wrong.

the base page is just a bunch of js that engages in a more or less endless loop of async xhr. I'm not positive if the spinner is supposed to spin when async xhr is going on.

It ... depends.

XHR does background loads (which ought not to spin the spinner), I thought, unless people are using progress listeners or some such.

But is the XHR what keeps the spinner going in this case?  Seems to me like it's the fact that the page is rewritten with document.write() (with an implied document.open() not followed by document.close()).  As in, this is a duplicate of bug 81980 and company.  And for that matter, of bug 771270, on the same URI.
