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**.
