> It's possible to somewhat bound the amount of load accepted into the cluster 
> by bounding the number of in-flight requests and request bytes.
> An implementation might do something like track the number of outstanding 
> bytes and requests and if it reaches a high watermark disable read on client 
> connections until it goes back below some low watermark.
> Need to make sure that disabling read on the client connection won't 
> introduce other issues.
