4# Performs the SHA1 sum of the whole datset.
5# This is useful to spot bugs in persistence related code and to make sure
6# Slaves and Masters are in SYNC.
7#
8# If you hack this code make sure to sort keys and set elements as this are
9# unsorted elements. Otherwise the sum may differ with equal dataset.
