module Persistent_singleton: Persistent_singleton
Implements a value that is either in a file, or in memory, but not both. Is used by
live and the friend to store sequence numbers and counters. If the value is moved to
memory, changed, and then the process crashes, the file will correctly reflect that
the value has been lost.
