No, this information is not stored in .rec files.

It would work if you let those john's run in the foreground (as long as
you run just one at a time anyway), but apparently you background them
(such as by ending the shell commands with "&")?

Why not run 4 instances then (or even 8 in case you also have 2 logical
CPUs per core, which is common)? If you're worried about impact on your
computer's interactive response time, then the "Idle = Y" setting
(default) should take care of that just fine.
Be sure to use separate --session names for the 4 instances.

Sorry, I don't understand what you mean here. The HUP is only needed
right before you query the --status.
