Details

With many tabs open, Olli sees a very long first slice of the CC, and most of the time is being spent iterating over the JS holders table.  If we move the purple buffer clearing before mJSRuntime->TraverseRoots() we should be able to incrementalize it safely.  This might involve turning JS holders into a multi-level hash table.
