No handlers could be found for logger "trollius"

[GregEremeev]

Most likely it's trollius bug, but may be you advise how resolve this issues.

This occur when I try launch example (examples/asyncio/websocket/slowsquare, server_py2.py and client.py)
Issue arise when I launch the client while server_py2.py already launch. Message(No handlers could be found for logger "trollius") appears in console(server_py2.py) and interaction between client and server stops. This behavior doesn't repeat always, but often.

Okay, figured out why.

On py3.4, this would usually raise something and log it. On py2, it does not log it, and it goes unhandled and breaks the execution flow. It happens "often" because of the "if x > 5, raise()" behaviour.

And then it froze.
