I'll have a look at this later today but, as you say, Linux to Linux
works, and getting the key wrong certainly breaks it (and without
setsockopt on the child, I believe). So some MD5 information is
getting copied from listening sockets to children.

Also note the MD5 on Linux is pretty badly broken in the face of
packet loss at the moment. I have patches floating around to fix it,
but not in any trees yet.
