I've not really looked at how Tomcat does its logging, but do we have an
opportunity to do what, say, syslogd does when it emits messages like
"Last message repeated X times"?

If the logger could keep a reference to the last log message and do
comparisons, this would be possible. On the other hand, reducing the
performance of logging isn't a popular thing to do.
