Log:
  Pick UINT_MAX / 100 as an upperbound.

  The fix that I applied in r286798 is already good, but it assumes that
  sizeof(int) > sizeof(short). Express the upperbound in terms of
  UINT_MAX. By dividing that by 100, we're sure that the resulting value
  is never larger than approximately UINT_MAX / 10, which is safe.
