But it looks like things in Winsock has improved in 10 years. Experimenting
with using WSAPoll()' in select.c, it works fine except for the 'POLLPRI'
bit (throwing 'WSAEINVAL').
Is there a compelling reason to switch over to WSAPoll()?
It took a long time before we found that poll issue the last time. If there is
an edge case still where they aren't compatible, I can imagine it won't be
easy to reproduce but might introduce strange hard-to-debug side effects down
the line.
Since we don't know in which Windows version the function was fixed, we might
still have curl users with broken WSAPoll implementations - even if more
recent versions work better.
Perhaps this could be configurable? Like in nmap --nsock-engine=poll, nmap
--nsock-engine=iocp etc?
I don't think so. When would a user ever try to use that option? Who would
even understand it?
