We tried to solve thundering herd problem wih cache-requester module which I have not committed yet. It is currently available on source forge.
I have not found enough time to work on it after summer of code was over as I was busy with my thesis, internship. now I have just relocated to calif recently. So, I should be actively working (in couple of weeks probably) on cache-requester soon once things settle down for me. meanwhile, feel free to use mod-cache-requester if you find it useful. Let me know if I could be of any help. -Parin.
