--- Comment #30 from Dan Kegel dank@kegel.com 2012-08-08 08:29:02 CDT --- This is why a tiny C test case is needed. It definitely sounds like a standard TCP/IP behavior (if you haven't read http://www.kohala.com/start/tcpipiv1.html yet, please do, it's a pleasure!). But since Bruno's sure it's not standard, the burden is on him to make a tiny plain C test case that illustrates the problem.
