There's a similar issue with nuclear reactors, which is that
there are so many blinky lights and such that it can be
impossible to spot or prioritize problems in a failure scenario.
I know there have been articles written on revisions of user
interface design in reactors specifically to deal with this
issue, and I suspect the ideas are applicable to error handling
in general.
