I think this tool must share a lot techniques and use cases with rr. I wonder how it compares in various aspects. https://rr-project.org/ https://rr-project.org/ rr "sells" as a "reversible debugger", but it obviously needs the determinism for its record and replay to work, and AFAIK it employs similar techniques regarding system call interception and serializing on a single CPU. The reversible debugger aspect is built on periodic snapshotting on top of it and replaying from those snapshots, AFAIK. They package it in a gdb compatible interface. Hermit also lists record/replay as a motivation, although it doesn't list reversible debugging in general.
