What makes a system be self-sustaining?
Is it:
 -  checking for errors and correcting?-  e.g. ecc memory, assertions in code, etc.
 
-  having a separate thread that maintains some system properties?
-  a network of cooperating processes that pass information to tune their behaviour?-  e.g. internet routers exchanging route information via BGP
