It is not mad idea - 2 CPU servers are not sugnificantly more expansive as 1CPU (and notice, we count P-IV MMultiThread as 2 CPU) but increases system redundancy to the run-away processes. Of course, it is not hardware redundancy, but it REALLY works.

What a mad idea.
Intel dont do fault-tolerant SMP.
Running SMP will lower your MTBF just by fact that you now have 2 CPUs. Then there's fact that you're far more likely to hit bugs in OS with SMP than uniproc.
SMP for reliability? Unless it's a multi-million zSeries, What a mad idea...
