That creates 10 distinct generators, which can be passed out to 10 distinct
threads. The generators don't share state so can be called safely in
parallel. So long as no thread calls its \code{g.random()} more than a
million times (the second argument to \function{create_generators), the
sequences seen by each thread will not overlap. The period of the
underlying Wichmann-Hill generator limits how far this technique can be
pushed.

Just for fun, note that since we know the period, \method{jumpahead()} can
also be used to "move backward in time":
