+	       Set scheduler wake cleanup threshold. Default is <c>medium</c>.
+	       This flag controls how eager schedulers should be requesting
+	       wake up due to certain cleanup operations. When a lazy setting
+	       is used, more outstanding cleanup operations can be left undone
+	       while a scheduler is idling. When an eager setting is used,
+	       schedulers will more frequently be woken, potentially increasing
+	       CPU-utilization.
+	     </p>
+             <p><em>NOTE:</em> This flag may be removed or changed at any time without prior notice.
