I wonder if some "stop file" approach" would work here.
It comes down to having a shared "stop condition".

But then each iteration (or group of iterations, etc.) needs to check,
at least at the start, if that flag went up.

And if each iteration can take multiple seconds,
it should also check at loop borders,
without slowing things down too much.
(so no free lunch)


Examples of such stop-conditions:
- shared (error-count) variable is non-zero
- file doesn't exist
- file exists
- file is touched
- file is non-empty
- pipe is non-readable
(etc., just select the fastest)
