Bug 1449033 showed that tracing jsids during cycle collector traversal can be extremely slow. The cycle collector does not care about jsids. Thus, we may be able to get some additional performance wins in the cycle collector by eliminating more of these.

I'm not clear on what exactly is the slow part, so I don't know how early we have to start avoiding getting the jsid.
