This patch ensures that the shutdown procedure can complete due to the fact we don't kill kernel processes anymore, and only stop the scheduler from running after the filesystems unmount procedure. We also need kernel processes during the shutdown procedure, because we rely on the WorkQueue threads to run WorkQueue items to complete async IO requests initiated by filesystem sync & unmounting, etc. This is also simplifying the code around the killing processes, because we don't need to worry about edge cases such as the FinalizerTask anymore.
