OK, this is done in CVS.  Incidentally, removing the silly busyloop
bug has greatly improved the efficiency of SSH connections!   (Amazing
eh? :-)

My standard linux-2.5.68 kernel benchmark build over three machines on
100Mbps now takes 237s over SSH and 161s over TCP, so it's still quite
a lot slower.
