Well.... I took the .c file mentioned previously, and compiled it on a
Solaris 10 8/11 instance. The 25-odd sockets it created *were* listed
in the output of netstat -an -- local address as *.<portnum> remote
address as *.* and a state of "BOUND."
A FreeBSD (rev 8 IIRC) netstat -an seems to display them in a state of
"CLOSED." I didn't check HP-UX 11i v3 or AIX 6.
