Interestingly, the NSE/UDP bug that David and I encountered on
Windows the other week seems to have gone away when poll is used (it
still hangs if the nsock engine is forced to select). This
presumably explains why I was only able to reproduce this on Windows
and not Linux. This should be less of an issue once Windows uses
poll by default, but it would be nice for the bug(s) to be fixed as
I presume it'll affect other systems that still use select.

That's interesting. I tried --nsock-engine=select on Linux, and I
couldn't reproduce the hang. So somehow it is a result of both Windows
and select.
