I'm pretty sure we need to apply the changes from http://trac.webkit.org/changeset/85375 to V8GCController.cpp, or at least carefully consider them.  I have not verified exhaustively that there is a leak in the V8 codepath but it seems fairly likely that there is.

Ideally we'd share the implementation of "should this node be protected from GC even if it is otherwise not reachable" between engines.
