+      <p>An important missing piece of the RCTL resource limits
+	mechanism was the ability to limit disk throughput.  This project
+	aims to fill that hole by making it possible to add RCTL rules for
+	read bytes per second (BPS), write BPS, read I/O operations per
+	second (IOPS), and write IOPS.  It also adds a new throttling
+	mechanism, to delay process execution when a limit gets hit.</p>
+
+      <p>The project is at the late implementation stage.  The major
+	piece of work left, apart from testing, is to integrate it with
+	ZFS.  The project is expected to ship with &os; 11.0.</p>
