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

Yes, to the most part. We'll likely a need a follow up to provide data to the pre-emption

> The current implementation is a simple queue - whichever query wins the race to submit
work to a daemon will execute first.
> A policy around this may be useful - potentially a fair share, or a first query in gets
all slots approach.
> Also, prioritiy associated with work within a query should be considered.
