Say, on a slightly different subject... but still having to do with
setsockopt(IP_TOS)... is it intentional that system call effectively
does nothing if the socket is in listen(), connect(), or bind() states?
In other words, you have to issue the setsockopt() immediately after the
socket() call, or it doesn't do anything.
As I remember, that's slightly different semantics from BSD, which
allows you to change the markings on a bound or listening socket.
I've not walked through the kernel sources to see why this is.
