RFE: bash should have a TID varuable that returns the vakue of gettid(2).
If the bash devs are too busy for this like the idea, I could write

Are you sure that'd help? Parallel runs bash in a bunch of subprocesses,
so looking at PID would suffice to distinguish jobs. Are you sure you
weren't seeing an invariant PID because you were letting the PID
variable expansion happen too early?
