I presume this is only for "blocking" sockets? I cannot at least off
the top of my head see how a stack could offer it on non-blocking sockets.
The test seems to be based on sending a big message. In this case,
on non-blocking sockets, the send call will return partial status. The
return from the system call will be less than the number of bytes requested.
Right, and at that point it is already too late to do anything about
keeping some other thread of execution from shoving _its_ bytes into the
socket before the rest of the first sends' can be put there.
(Perhaps I'm preaching to the choir)
