 The LDAP problem has been fixed, but the new sshd-session wants to exec =
 sshd-auth with stdin/out the network socket so the hijack
 code tries to dup(128, 0) and fails in:
 
         if (fd_isrump(oldd)) {
                 int (*op_close)(int) =3D GETSYSCALL(host, CLOSE);
        =20
                 /* only allow fd 0-2 for cross-kernel dup */
                 if (!(newd >=3D 0 && newd <=3D 2 && !fd_isrump(newd))) {
                         errno =3D EBADF; <-----
                         return -1;
                 }
 
 The server client portion of the test works without rump...
