it would actually be possible to do this legitimately with nonblocking
connect calls, no? or is it simply assumed to be invalid since "who
in the world would do such a thing?"
the tcpip stack has things like SO_REUSEADDR and SO_REUSEPORT that
would make this easier, and if a process forked after calling bind and
tried to connect back to itself (again, why?), wouldn't that
accomplish a legitimate connection?
