As far as I can tell systems that have less than 4GB are more often hurt
by prefetched than helped.  On i386 systems and systems with less than 4GB,
prefetch is now disabled by default. I've added a prefetch enable tunable, to
enable prefetching for those systems. The prefetch disable tunable will continue
to unconditionally disable prefetching.
