LGTM

Though I still don't get what purpose is served by starting the other thread at
this point.

Thanks. You are right, it is overkill at this point to have a separate listener
thread. I'll need it in the future though and don't want to throw away that code
in the meantime.

I agree.

It is just that we are pretty early in the development of the protocol and it is
not clear how the multiple isolate situation is going to evolve. When that
becomes clear it is possible that we may conclude it is better to re use the
messaging infrastructure we already have.
