My Changes Action
This is the development page for the my changes action.
The php code:

The above code doesn't sort the pages properly when sorting by time.
I have re-coded the action like this:

For a comparison of the both versions see TimosChanges. That page uses the above code, but statically assumes TimoK as user, no matter if you are logged in or not.
Thanks to JavaWoman who helped me a lot tonight with questions and ideas. Without you I couldn't have done this.
The above code seems stable, safe and fast (225 out of ~260 rows fetched in 0.07 seconds compared to 0.25 seconds with the old code), but it's 1:35AM as I am writing this, so I would be happy if some others could test it on their own wikkas and let me know if there are any problems.
