Please run some tests how does your container perform compared to
containers we already have. If it is roughly on par with them, random
access is a great bonus and I would be all for using only the new one.

Janek could comment on this, perhaps? How about
physicalActionContainerResetter, that is normally run at the beginning
of each iteration; don't you have problems there?
