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.)
