My UDP-specific proposal at
<http://trac.sacrideo.us/wg/wiki/DatagramChannelsCowan>, has two
constructors, make-datagram-channel for socket() followed by bind() and
make-output-only-datagram-channel for just socket().  I believe this is
a better division of labor than the standard one.

Like R[67]RS call-with-port, it makes sure the socket is closed if proc
terminates normally, a non-trivial difference.

IMHO "unix" (which is a trademark) should be suppressed in favor of "local"
in all these names.
