`ctx` is a defined function parameter that's always overwritten, i.e. never in `kwargs`

so what are you suggesting?

[jimdewees]

The docstring for zmq.Context.instance provides a good implementation example.

[sphaero]

You're not very verbose. Are you suggesting that:

ctx = kwargs.get('ctx')
if ctx == None:
    ctx = zmq.Context()
self._ctx = ctx

should be reduced to

self._ctx = ctx or zmq.Context()

That would fix the issue that you are trying to get ctx from the kwargs dict, whereas it is defined as a proper keyword argument in the __init__ method definition.
