The 'DELETE FROM' actions is good enough fix for a defect we wanted to nuke 
early enough, before Linux Tag.
I've discussed this logic a bit with Till before implementing it.
Only 'completely' broken items are removed.
We'll want to find out a reason for their existence anyway.
Moreover, mmmap implementation (!Windows default) is unaffected.

It's my habit for porting to Qt4, backed by reasons described at 
http://doc.trolltech.com/4.4/qhash.html#details
http://doc.trolltech.com/4.4/containers.html#algorithmic-complexity

Here the data set is small, so if you prefer I can go back to QMap.
