Thanks for the patch. That's a nice bug you found.
I fixed things slightly differently, but mentioned you in the commit:

Hello Jason,
your bugfix works fine for jumbo packets but not if the Windows socket
is flooded with " nc -u <IP-Addr:port> < /dev/urandom ".
best regards - Sascha

Hi Sascha,
Oh, boy, that's embarrassing. Fixed here:

Thanks again for the report.
