Sigh.  Apparently I was not very clear though I have just been for two
days in Germany now.  You have a 15-bit non-repeating random number
space.  After you have exhausted that space, you toggle the high bit
and start over with a different 15-bit non-repeating random number
space.  And so forth.  At the end, you still have a 16-bit space.
