fwiw, I still haven't found a single reference (SUSv2 spec, man- pages, Stevens, the original BSD papers) that says that a blocking socket may do anything but sending all the data, or fail.

The Solaris manpage sort of seems to indirectly suggest that it might conceivabley be possible:

 EMSGSIZE  The socket requires that message  be  sent  atomi-
           cally, and the message was too long.

Which suggests that some types of socket may not require the message to be sent atomically. (TCP/IP, for example.)
