Some applications...
How about communication, TCP uses 32bit counters to sequence packets, the
packet following 32 ones is zero. Trading (stocks/futures) cards are
numbered 000 to 999. Database rows... Any counter that can wrap to zero.
You want to be able to sort items arriving out of order and detect missing
items. The TCP folk call this sequence space arithemtic. See
/usr/include/netinet/tcp_seq.h
