Figured it out and deleted the original posts because they were effectively noise in the Google Groups. It was developer error. I was looking at a test input that would've generated more branches than free matching slaves, but mistakenly rebuilding my job with another test input where threads < available matching slaves.
When I fed it the "threads > slaves" input, parallel worked as expected: 5 concurrent threads, then 5 more, etc. until all branches in the map were executed.
