Thanks a lot for the tips Vernon.

I am counting query_type+query_name, implemented as:

set qhash [b64encode [md5 "$q_type:$q_name"]]

I guess that's my "state blob". Is that good?

I will lower the drop window to 10 or 15 seconds and see how that
behaves. Query responses would be my next phase.

I am also dropping everything, during the drop window, as I did not
want to keep the query info for too long, but since I will lower the
window, it might be feasible.

Thanks a lot,
Mohamed.
