987912 - Collect parallel arenas between every iteration rather than every chunk

Status: RESOLVED FIXED

(Core :: JavaScript Engine, defect)

Description

[Niko Matsakis [:nmatsakis]]

Currently we collect parallel arenas between every slice. This is too coarse for some benchmarks. It would be better to do it between every iteration for the time being; this subsystem is in need of some longer-term tuning as well.
