Possibly so. But unless we are to introduce a "thinkfest", how do we know
when such a better time would be?

Lately commit-fests have been basically a continuous thing, except during
beta which would be an even worse time to discuss it. It think that
parallel execution is huge and probably more likely for 9.5 (10.0?) than
9.4 for the general case (maybe some special cases for 9.4, like index
builds). Yet the single biggest risk I see to the future of the project is
the lack of parallel execution.
