+	       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.

+	    Scheduler threads will now by default be less eager
+	    requesting wakeup due to certain cleanup operations. This
+	    can also be controlled using the <seealso
+	    marker="erl#+swct"><c>+swct</c></seealso> command line
+	    argument of <seealso
+	    marker="erl"><c>erl(1)</c></seealso>.</p>
