Summary

This patch introduces a new environment variable to force monotonic behavior for users that absolutely need it. This is in anticipation of a 5.0 spec change that uses non-monotonic behavior for dynamic scheduling by default. Fixes for that and the actual switch are coming soon.

Patch by Johnny Peyton.
