So, the page load times for voodooextreme shot up enormously overnight (from ~5 seconds to ~45seconds, on Mac and Linux, but oddly not on win98). The above test page simply reloads the voodooextreme content continuously and blats a few dump statements to give a clue about progress in building the page. When you load that page, you can see that this is continually computing the whole time (on Linux). [i.e., this is not like other times, where the onload just wouldn't fire]. dbaron did a jprof run of a build that did not have pavlov's changes from last night, and sees a lot of work being done in nsCSSFrameConstructor.

hyatt, bryner, and I debugged this and came up with a patch. The problem was uninitialized variables. It might have been responsible for many of the assertions today as well.
