+ * poll: This plugin turns out to have edited pages w/o doing any locking.
+ Oops. Convert it from a cgi to a sessioncgi hook, which will work
+ much better.
+ * recentchanges: Improve handling of links on the very static changes pages
+ by thunking to the CGI, which can redirect to the page, or allow it to be
+ created if it doesn't exist.
+ * recentchanges: Exipre all *._change pages, even if the directory
+ they're in has changed.
+ * aggregate: Lots of changes; aggregation can now run without locking the
+ wiki, and there is a separate aggregatelock to prevent multiple concurrent
+ aggregation runs.
