Hi, could you retry on master?

[bsullivan19]

Bug is still present on latest pull from master. Tried on Ethernet and Wireless NetworkInterfaces and issue is present on both.

I'm not sure that this is fixable. We use windows native WaitForMultipleObjects to wait for incoming packets which... you can't cancel from within Python. This is a limitation we can't really work around without compromising on select() performance.

The workaround would probably be to use a timeout parameter. Like timeout=1.
