Any work that is lengthy and not cooperative is better served with a task
on the dirty scheduler. That way, we avoid blocking the scheduler thread
which would mean we would stall processes. Long-running garbage collections
are one such thing, so they can get backgrounded on the dirty scheduler.
Once the GC is done, the process is moved back onto a "normal" scheduler.
