AFAIK there is no portable way to reject incoming connections without
calling accept(). However, accept(2) states:
One can obtain user connection request data without confirming
the connection by issuing a recvmsg(2) call with an msg_iovlen of
0 and a non-zero msg_controllen, or by issuing a getsockopt(2)
request. Similarly, one can provide user connection rejection
information by issuing a sendmsg(2) call providing only the
control information, or by calling setsockopt(2).
Is this really true? A quick experiment with recvmsg() seems to
indicate it is not, at least not for TCP sockets.

P.S. Anybody who claims that this works is encouraged to provide
proof in the form of code... :-)
