  I'm sorry, but that's akin to saying that implementing SMP on i386 is more
of a pain than it is worth and if you really want a good SMP implementation
you should just buy a box from Sun. A legitimate engineering problem was
presented, presumably there is a legitimate engineering solution. Finding one
that everyone can agree on is another thing entirely... :)
