Fastest pseudo-random number-generator: erlang:statistics(io) ?

[Thijs]

The new nif (native implemented functions) provide a great alternative
to generate random numbers and timestamps, much faster than the Erlang
alternatives!

The speed is about 1/2 to 1/3 of statistics(io), but still much faster
than erlang:now().
I simply used time(0) for the nif_now() and gettimeofday(&tv, NULL)
for the nif_random() functions.

nif's are a great addition to the language!
