Targeting specific form element with a4j:support reRender?

Hi

In the basic code snippet below, how do I get the a4j:poll to re-render only "clock" (short of using separate forms)? What I'm finding is that the entire form (main_form) is updated, causing the a4j:status to flicker at the poll interval.

 <h:form id="main_form">
 <h:panelGrid>
 <h:outputText id="clock" value="#{bean.time}"/>
 <%-- this updates both the clock and the entire form, causing status to flicker --%>
 <a4j:poll id="clock_updater" ajaxSingle="true"
 interval="1000" reRender="clock"/>
 </h:panelGrid>
 <h:panelGrid>
 <a4j:status id="status" startText="doing something" stopText="done"/>
 </h:panelGrid>
 </h:form>

Help much appreciated
Lance

For the record, I solved the like this with a4j:region:

<h:form id="main_form">
 <a4j:region renderRegionOnly="true">
 <h:panelGrid>
 <h:outputText id="clock" value="#{bean.time}"/>
 <a4j:poll id="clock_updater" ajaxSingle="true"
 interval="1000" reRender="clock"/>
 </h:panelGrid>
 </a4j:region>
 <h:panelGrid>
 <a4j:status id="status" startText="doing something" stopText="done"/>
 </h:panelGrid>
 </h:form>
