On an i386, "long" and "int" are both 32 bits, hence "long" has a
lower maximum count than "unsigned int". "unsigned long" might be
a better choice (to give a greater range on the Alpha).
In any case, at 1000 forks/sec, a 32-bit counter will still take
nearly 50 days to wrap. Lots of other counters will have wrapped
by this time.
