Drifting a bit, and perhaps not properly interpreting some of the TLAs, 
but I suspect that if we go back oh 20ish years or so, we could find 
similar calculations being put forth to show how very long a 32-bit 
counter would last :)  Perhaps it isn't too too early to start talking 
about > 64 bit counters...
