bq. Good discussion. I hope we are still on track with this design ?

The general mechanism seems fine, yes.

But if this issue will also enable it by default, then the details still need 
to be nailed down.  What requests go to what queues, and which queues can be 
safely lowered to limit concurrency and increase throughput, and which queues 
need to be configured near upper bounds to work correctly.

Or we could split it up and limit this JIRA issue to the mechanism and punt 
enabling with good defaults to another issue.
edit: or enable but have high limits for all queues before we figure out what 
good defaults are (that should not be worse than the current scenario).  I just 
don't want to go backwards by committing something with bad defaults on a 
promise that we'll figure out the right thing later.
