The last output from the pageloader was:

NOISE: Cycle 4: loaded http://localhost/page_load_test/pages/www.nih.gov/www.nih.gov/index.html (next: http://localhost/pa

(some sort of bufferring problem cut off part of the page that was next, I suppose, although given that buffering problem, we don't really know that there weren't more pages in the middle)

Slightly different stack, same problem?
Different stack - same bug?

If we just run this test over and over, can we get it to trip frequently? graydon might be able to give us some cheap instrumentation to help us find the underlying (and FF3.5-blocking) crasher...
Sounds like this hasn't happened for a few months.
