[Grok-dev] batching view

[modiadi]

Thank you,

I also foundz3c.table during the weekend.

I decided to use z3c.batching fpr the moment because I want to  
understand the details. I will use some kind of persistent list but I   
haven't decided yet.

I am still worried about the performance issue with a large collection  
of news...
