FYI, that's what I did. Test client ran across the network to the
server, so it could output on the console which transaction was last
reported commityted.

In a couple of cases, the server came up with a transaction the client
had *not* reported as committed. But I think that can be explained by
the commit message not reaching the client over the network before power
went out.
