Description

Attached is a simple python client that connects to a server and waits forever for a message to be received, reconnecting on connection failure.

When the server is restarted (in my case I'm using qdrouterd), the client reconnects then pins the cpu at 100%. It appears as if the BlockingConnection.wait() method in util.py is the source of the busy loop.
