Okay... I spent a few minutes tracing things, but need some guidance...

It looks like the send() (in wsocket.c::sock_sendto()) fails with a
WSAEWOULDBLOCK error. Anyone savvy to why this is happening?

I can do the following to make things work:


but that's inconvenient, and I don't think it works with broadcast datagrams.

Guidance appreciated!

Thanks for the wonderful community. I love Lua (anyone making bumper
stickers or t-shirts that say this?)
