russ is should be correct.

i think that dossrv's quirks are surprising.  the
redirection in 9fat: is superfluous since 9fat opens
/dev/null on fds 0 and 1 and it makes this surprise
move for fd 2:

	if(!chatty){
		close(2);
		open("#c/cons", OWRITE);
	}

that's downright antisocial.  maybe there's a good
reason.  but i can't think of one now.
