87f7fdfd - Allow instruction counting to use shared memory as a staging ground. (And a couple other tweaks.) (#56711)

Allow instruction counting to use shared memory as a staging ground. (And a couple other tweaks.) (#56711) Summary: This is actually something I discovered a while ago with the wall of serotonin. It was really easy for large scale runs to get bottlenecked on disk access. I have a hack in the working files of that machine to use `/dev/shm`, but I figured I should formalize and actually make a respectable utility. I also added a param to tweak the run cadence and print when a CorePool is created; these are just to make the CI logs a bit nicer. (A printout each second on a 40 minute CI job is a bit much...)
