I guess I've never really used parallel for anything that was bound by the dispatch speed of parallel itself. I've always use parallel for running stuff like ffmpeg in a folder of 200+ videos, and the speed in which parallel decides to queue up the jobs is going to be very thoroughly eaten by the cost of ffmpeg itself.

Still, worth a shot.

I have to ask, was this vibe-coded though? I ask because I see multiple em dashes in your description here, and a lot of no X, no Y... notation that Codex seems to be fond of.

ETA: Not vibe coded, I see stuff from four years ago...my mistake!
