Eventlet is banned from neutron-lib, therefore waiting for this
method to be exported to neutron-lib means waiting for ever. Now
one may argue that copying the method itself could be the way
forward, but that assumes that the neutron-dynamic-routing code
stands a chance to run on Windows. I suppose we can cross that
bridge when we get to it, but as of now, using monkey patching
without params is more than enough.
This is one step of many to make at least one repo neutron free.
