This assumes that your old world can work correctly with your new
kernel (remembering that `make world' is seen as our standard system
stress test).  The whole justification for the `install the world
then upgrade the kernel' approach has been that we _do_not_ guarantee
this.

We've never required this before.  I managed to convert from 2.2.6 to
-current using `make upgrade'.  Why should I need to FTP a kernel
from another machine to go from 3.x to 4.x?
