com.yahoo.io.FatalErrorHandler

public class FatalErrorHandler
extends Object

What to do if a fatal condition happens in an IO component.

TODO: We need to re-think this design a bit. First off, we probably need to make the interface an abstract class or a pure interface type. Second we provide a few default implementations which are named after what policy they implement -- like SystemExitOnError etc. Also, runnables that have fatal error handling capability should probably implement a standard interface for get/set etc. Also, we should encourage application authors to provide their own, application specific error handlers rather than relying on the default.
