+	    Specifically, prevent use of a physical CPU for a significant,
+	    perhaps indefinite period.  If a host watchdog (Xen or dom0) is in
+	    use, this can lead to a watchdog timeout and consequently a reboot
+	    of the host.  If another, innocent, guest, is configured with a
+	    watchdog, this issue can lead to a reboot of such a guest.</p>
