Re: [infinispan-dev] [Cloudtm-discussion] Primary-Backup replication scheme in Infinispan
Interesting discussion, but you either need to use failure suspectors, which are different
to failure detectors, or quantum mechanics. I suppose the only other choice is
omniscience, but I don't know how to do that ;-)

....still there are many real systems that are actually designed assuming perfect failure
detection... possibly relying on some dedicated hardware mechanism (which encapsulate the
perfect failure detection assumption) to enforce accuracy by forcing suspected nodes to
shut down falsely suspected nodes, e.g. http://en.wikipedia.org/wiki/STONITH.
