The SessionServerContextMixin raises SessionExpired, which would
be caught in the top level script (around the bit that looks like
"app.run(Request())"). I would have expected this to also occur with
RandomPage apps, but I can't immediately see the code path that would
result in this happening.

Dave is the expert on the RandomPage stuff - I had hoped he would spot
your message and reply. Unfortunately, it will be Tuesday at least before
he replies - he's on leave now.
