	From a former life, journals are A Good Thing: my smarter
	colleagues synchronized multiple copies of my horrible kludgy 
	database with each other by making them read each other's
	journals.  Timestamps gave us a weak ordering after
	some clock-skew estimation, and we never actually saw the
	expected race conditions when we suffered network partition.
	Turned out the changes had a natural locality of reference.

	I was **impressed**.
