    Is it possible to get, in a single operation, both the quotient and
    remainder in a fixnum division?  I have often wanted to do something
    like:

    (MULTIPLE-VALUE (QUO REM)
      (FLOOR A B))

So have I.  Unfortunately it is rather difficult to get this to work
since arithmetic is performed in microcode, and it is difficult to get
multiple values out from microcode.  The loss in calling the divide
code twice is not great unless you are doing very many bignum divides
of very large bignums very often.
