Details

Profiling parallel vs sequential, it looks like we end up getting killed on overhead with lots of small traversals (i.e. the one-off traversals from the frame constructor).

We should profile the overhead, see if we can reduce it, and figure out where the threshold is for the parallel traversal to be a win.
