Thank you for looking into this!

Chris Dumez arrived at a similar conclusion a couple of days ago while debugging a new crash (Debug Assertion) in pageCache after he added a new test. See Bug 143799.

I think your analysis is correct.

Chris updated DumpRenderTree to deactivate the pageCache between runs in <http://trac.webkit.org/changeset/182844>.

I think this change will also resolve this bug, but I haven't tried since his change landed.
