What does this checkin do? It looks like it is skipping doing some work 
that otherwise would be done.. Anyway, if Philikon is okay with it I'm 
okay with it too, but I haven't got the time to review it in detail now 
(about to go on vacation in a few days). Let's check it into the trunk.

Does mean that the FiveFormDemo doesn't actually work in the 0.1 
release, too bad. I wasn't aware that it was broken -- next time let's 
use a branch for additions which don't quite work yet.

Can we write a test for this change? Philikon?
