Running out of time to debug this today. I think this is a bug in CPython, in either socket or select module. When I inject some debug code in selectors.py and replace KQueue with select(), I can see that the server thread's selector stops working at some point due to a EBADF error. I think something similar is happening with the KQueue selector -- at some point it just stops to return events correctly. Again, I might be wrong about this all, but this is what I think after 2.5 hours of debugging.
