title: I can't figure out what exactly Meteor {{#isolate}} is. Are there any examples?
body: <p>How do I use {{#isolate}} ?</p>
  
  <p>If I make a page with a bunch of templates, like:</p>
  
  <pre><code>{{&gt; page1}}
  
  &lt;template name="template1"&gt;reactive source1&lt;/template&gt;
  &lt;template name="template2"&gt;reactive source2&lt;/template&gt;
  &lt;template name="template3"&gt;reactive source3&lt;/template&gt;
  &lt;template name="template4"&gt;reactive source4&lt;/template&gt;
  &lt;template name="template5"&gt;reactive source5&lt;/template&gt;
  
  &lt;template name="page1"&gt;
      {{&gt; template1}}
      {{&gt; template2}}
      {{&gt; template3}}
      {{&gt; template4}}
      {{&gt; template5}}
  &lt;/template&gt;
  </code></pre>
  
  <p>If each single template has content that updates, will it rerender the whole page each time? How do i stop that from happening?</p>
  
  <p>Should I use <code>isolate</code> in this situation?</p>
  
  <p>If I bind any helper to these templates, like:</p>
  
  <pre><code>Template.template1.rendered = -&gt;
      console.log 'rendered at: ' + new Date().getTime()
  </code></pre>
  
  <p>it will render at least 5 times because I have 5 reactive sources. If each of them includes a
  reactive list, it will be rendered docs.length times.</p>
  
  <p>I can't control single template instances.</p>
  
  <p>Sorry about my english.</p>
