A novel approach is to remove all power from the system, which
removes most system overhead so that resources can be fully devoted to
doing nothing. Benchmarks on this technique are promising; tremendous
amounts of nothing can be produced in this manner. Certain hardware
limitations can limit the speed of this method, especially in the
larger systems which require a more involved & less efficient
power-down sequence.
An alternate approach is to pull the main breaker for the
building, which seems to provide even more nothing, but in truth has
bugs in it, since it usually inhibits the systems which keep the beer
cool.
