Change subject: IMPALA-5158,IMPALA-5236: account for unused buffer pool reservations
......................................................................


Patch Set 6:

Right, I think if I was starting from scratch I'd do something closer to what you describe
instead of adding the metrics hook.

It would be nice if we had a way to separate out metrics that are directly actionable from
those that aren't. I agree people sometimes see metrics and think that they need to optimise
them.

I suppose we could tweak the wording to be something like "Unfulfilled reservations" or "Pending
reservations", which is less likely to sound like an inefficiency.
