Yes, I think this at least gives a simple model for what to expect.

Any other more conservative model might have the advantage to preserve
more freedom to change the GC/thread policy in the future, but will
also need to be much more complex.  Besides, we wouldn't know now what
kind of cautions are important to think about...
