Thinking about systemic risks

After spending few years in engineering safety systems for nuclear power plants and the transmission grid - I can say I have a deep sense of appreciation for complex systems.  To me, they are as close as to the proverbial butterfly that flaps its wings in the Amazon causing a storm in Japan.  One of the key design criteria in the nuclear power plant is that it has to be able to shutdown safely if an adverse event occurs.  Thinking for banks, I believe the same can apply.  In case of a major macroeconomic (or other) shock, the bank has to design ways to safely "shutdown" and wind-up without causing a cascading set of reactions resulting in a financial "meltdown" or "blackout".  Anil Kashyap in his FT piece talks something in those lines.
