Yes I know, I did not say that my solution yet elimates this problem. It just works quite well for me as in my case I got some collections that got a very high load for an hour or so and then most probably no other collection is touched and after this period this collection is not touched for even days by anyone. But I'll try to find time to think about a more sophisticated solution, I'll tell you if I got one.
