# Returns a context-dependent position object that has the following methods:
# (includeng Comparable mixin is preferable)
# - all comparison operators (<=>, <, <=, >=, >, ==, !=)
# - to_s

# Public Interface: Back to last known safe source pos
#
# Returns a source position object
#
# A source pos may not be restart-able from the very position because
# there may be preceding records necessary to restart the source log
# playback. This method returns such a 'safe' position from which
# the source log can be played back.
