more sockets... sockets tomorrow, too.........
i do like send and recv as a pair, though. mostly because they're the same length. for that reason, i often pair out with inp rather than in
anyway, this is effectively just a read/write pair, but with flags

>MSG_CONFIRM
Has anyone ever used this, or is this just an insane micro optimization?

it seems useful primarily for drivers and not most user code
