Yes, and after you do a select (or poll) before accepting. But... linux
won't work that way because if you have a socket listening for ipv6 it
will take the ipv4 connections and won't let you bind to the same port
for ipv4. USAGI worked right until some time ago when they went down
the same road.

That's the ugliest part of programming with IPv6 (and that's because
the ugly IPv4 mapped addresses)
