OSError: [Errno 9] Bad file descriptor

I came across this exception when I try to close socketio Client.

Exception in thread Thread-17:
Traceback (most recent call last):

The reason maybe is that it is sending STOP packet after the connection have been closed.

You must be using an old version of the python-engineio package, because this was fixed a few months ago. See miguelgrinberg/python-engineio#177.
