[ shrug... ] Call me Cassandra. I am not concerned about what has or
has not been discussed. I am concerned about what effects we are going
to be blindsided by, a few months from now when it is too late to
conveniently add a way to detect that the system is being run as an HS
master. If we design it in, perhaps we won't need it --- but if we
design it out, we will need it. You have heard of Finagle's law, no?
