+## perform a series of scrub related state change tests. As of now, there'
+## no way to check if a given change has been correctly acknowledged by
+## the scrub process as there isn't an _interface_ to check scrub internal
+## state (yet). What's been verified here is scrub state machine execution
+## w.r.t. locking and faults.
