The issue the Guide talks about is application code that tracks peers.
I've not tested, and it's not documented, how the ROUTER socket
manages its internal tables. I'd expect the router socket to clean up
its internal tables when clients disconnect. So if it's not doing
this, we need a test case.

That may be enough to fix the problem.
