[net.lang] loops counting down

pjw@rabbit.UUCP (peter weinberger) (01/22/84)

C does not encourage loops counting down (although it must
plead guilty on register declarations):  in our kernel (modified 4.1)
there are exactly 7 counting-down loops [matching for.*--],
2 of which are maintaining first-in-first-out, one is a cheap decimal
conversion, 3 have early exits, and only one (in vmpt.c)
of which is gratuitous.
