At this point a rogue client can pretty easily bring down a cluster, so...
We could be sanity check the priority on the server side.
I don't think that we can anticipate all of the factors that users will want to include. So
it's easier to let users add their logic on the client side rather than the server side.

Fair points.. For now, let's make the priority an optional field in the RPC and let the client
send it. That would give us enough wiggle room to switch to an alternate implementation (and
at that point maybe make it configurable on whether we would honor client's notion of priority..).

bq. I don't think that we can anticipate all of the factors that users will want to include

Of course.. I meant to just give examples of other things that the server might want to consider
before assigning priority to a request...

> RPC format is changing for 0.96 to accomodate our protobufing all around.  Here is a
first cut.  Please shred: https://docs.google.com/document/d/1-1RJMLXzYldmHgKP7M7ynK6euRpucD03fZ603DlZfGI/edit
