You are right, I had not realized there was a race condition here.
What happens if shutdown() is performed but not close()?

The receiving worker thread is less than 60 lines, the sending one is
100 lines because of the rate control code that can certainly be
factored. All in all, that would not be that terrible, and if done
cleanly can be reused later for more generic code.
