This is OK for mainline, with the minor modification recommended by
Zdenek, that it need not test current_loops->num anywhere.
Many thanks to Andrew for fixing the bootstrap failure, and to both
Zdenek and Paolo for confirming that the fix is correct.
Now the task of figuring out why this wasn't caught in testing prior
to being committed. Presumably an incompatible change to loop handling
has collided with fwprop during stage 1?
