Created attachment 622598 [details] [diff] [review]

I noticed that the times from the error console were screwy in some cases. The problem is that we tell the statistics code that we're entering the mark phase, and then tell it again a little later. The code isn't designed to handle re-entry.

This patch asserts that we never re-enter a phase. It also fixes the case I found, where IncrementalMarkSlice enters the mark phase, and then re-enters it in EndMarkPhase.
