------------------------------------------------------------------

I've noticed that replication can trigger this quite a bit as the sink applies 
the shipped edits. Should we make a distinction between normal clients and 
replication clients and apply two separate thresholds?

> Today, if a user happens to do something like a large multi-put, they can get 
> through request throttling (e.g. it is one request) but still crash a region 
> server with a garbage storm. We have seen regionservers hit this issue and it 
> is silent and deadly. The RS will report nothing more than a mysterious 
> garbage collection and exit out.
> Ideally, we could report a large multi-* request before starting it, in case 
> it happens to be deadly. Knowing the client, user and how many rows are 
> affected would be a good start to tracking down painful users.
