throttleRefresh not working

First of all thank you for your great effort and the package but it seems there is a problem whiith throttleRefresh.

I have dataset that changes a lot and throttleRefresh is not working. When my server received 100requests in a second, datatable starts to freeze.

If I'm on a page where the datatable created for the same collection which get update requests, Mongodb logs "subscription queries" repeatedly.

Start by reproducing the issue with a collection receiving many updates per second and a datatable displaying that collection. Inspect the throttleRefresh behavior alongside the repeated MongoDB subscription queries and datatable freezing. Done means rapid updates no longer cause repeated subscription queries or freeze the datatable.
