I suppose one solution would be for them to also destroy anything that
was nearly like themselves, but different (e.g., if there are 100,000
components, then if 99,900 < N < 100,000 of them are identical, try to
destroy the booger).  If we have some estimates of mutation rate, we can
derive a probability distribution for a harmful mutant's prospering.
Surrounded by huge numbers of correctly-functioning detectors, it seems at
first glance that the survival of a nasty strain could be made arbitrarily
small.  Of course, if the mutation involved just destroying everything, the
``good'' detectors might be too slow on the draw to do anything.  Sounds like
a Western...
