/* Handle large integers for calculating big tape lengths and the
   like.  In practice, double precision does for now.  On the vast
   majority of machines, it counts up to 2**52 bytes without any loss
   of information, and counts up to 2**62 bytes if data are always
   blocked in 1 kB boundaries.  We'll need arbitrary precision
   arithmetic anyway once we get into the 2**64 range, so there's no
   point doing anything fancy before then.  */
