Sure, you use user-space code to either put datagrams on top of
TCP or reliability on top of UDP. But, I don't think it should
be something done in user-space. I think SOCK_SEQPACKET should
be implimented on top of IP in the network stack along with
SOCK_DGRAM and SOCK_STREAM.
But that's just because I'm tired of running into problems
caused by the assumption that TCP is a datagram protocol, and
tired of hacking a datagram protocols onto the top of TCP to
fix those problems.
