Olaf Flebbe:

I had massive problems with tower.cxx, so I decided to doublecheck all
containers and iterators in order and found lot of potential problems.

Now I can fly with "debug on" of KSFO for minutes without problems.

The fix for AIMgr is from Mathias, but I reworked it. So blame me, not him.
