see how mozilla works? youtube video: https://www.youtube.com/watch?v=ytNlefY8PIE

this talks more about mozilla internals: rr uses seccomp bpf to do secure computation in filters, to record the syscall input and ouput, and records the results in logging. When debugging in following time, rr will replay the results from logging.

So rr will make the non-deterministic problemns become deterministic in debugging.
