Summary: history.js blocks gecko browser with 100% CPU when

CSS restyling code in most of the gecko-based browsers (in the
FrameManager::ReResolveStyleContext for the curious, see
https://developer.mozilla.org/En/Style_System_Overview) when displaying a
history page with larger number of revisions.
Everything is fine when histrowinit() from history.js is not loaded, i.e
removing the hook or blocking history.js load relieves the situation.
The problem occurs only at initial page load, further clicks on the history
page do not slow down the browser.
