That's an interesting question.  According to POSIX, it depends on
whether the socket is stream based or message based.  For stream-based
sockets (which is what we're expecting), it appears that that is true. 
For message-based sockets (which we're not expecting), recv is required
to return the length of the message, even if it's longer than "size"
(the extra bytes are discarded).
