I still don't understand why internal messages would be different. Is
that because you get only one inter-thread message instead of several?

I think it would be better to try to write a test that replicates the
problem you are seeing. In particular, testing GetQueueStatus instead of
message sequences is not very convincing to me, since it doesn't
properly show what's going on.
