It uses pipe(3), which actually returns an AF_UNIX socket, not a pipe; so the "no-RDWR" restriction is a lie.
The unixfd field of the Ropenfd is a lie; and the control-message should be used instead
Specifically call out in openfd(9p) (in addition to the existing call-out in 9pclient(3)) that there's no special version string.
