No it's not. The msg may be fully on disk and not in RAM, at which point
you have to issue a disk read regardless of whether the client is
embedded or not.

Furthermore, we do not store the message headers separately from the msg
body. Thus the only thing you're saving by getting one, not the other,
is network transfer. And given the average message body size, ethernet
frame size and the fact that we turn nagel off, I'm not convinced in the
average case you'd actually save anything at all, but I could be missing
something.
