Why do we wait for the full remainingMs instead of a shorter timeout specific to this step?
If we block here for the entire remaining shutdown window due to a stuck task, other cleanup steps may not run in time.

Why is shutdownNow() not used here?
Without it, non-daemon threads may remain running in a worst-case scenario, potentially preventing the JVM from shutting down.
