Thanks for doing this work.

It's very disappoing that the whole of the data sending system
calls need to be duplicated into this new tcp_friends.c file.

My entire hope was that we could integrate the logic into the
existing sendmsg/recvmsg implementations.

Please reimplement things this way.  With so much code duplication
I really cannot justify putting this feature in as-is.
