How about readfrom and sendt on the same file descriptor at the same time? Yes, but assume two threads A (writes a one message containing "aaaa") and B which (writes two messages "b" and "c"). You can be assured that B's data won't show up inside A's message: ie. never aabaa but you can not assume anything about the order they will be received. If you want more detail read the book. W.
