Reverts a fix for a bug in the scheduler where it let a thread going unscheduled continue running if there are no other non-running-now scheduleable inputs. This triggered too-frequent all-unscheduled cases and the current timeout for those is too high, causing tail delays. We'll re-instate the fix once we add an early exit feature for that scenario.
