If it isn't actually alive anymore, it won't be able to serve
requests, and by the same token won't be able to maintain its matrix
of producers and consumers.  Once that state is reached, the system
goes into a "fail-safe" mode.

Sure, fail-safe mechanisms can fail.  But being overly creative about
the software bug doesn't help either.
