Thank you Roman. I worked in your feedback; while testing I found an off-by-one, and a minor flaw with tracing.

About your procfs question, this should be safe. We only do this once, at start, and have a reasonable fallback. Note that hotspot already reads from this file for other purposes, it seems to work well.
