nsure that the current traversal map is the next
 traversal map of the previous traversal.  Here is an example for
 illustration purposes only.</p>

 <blockquote>

 <p>Consider an initial request to the faces lifecycle</p>

 <p>Traversal N, execute phase: skipped on initial request.</p>

 <p>Traversal N, render phase: flash access goes to flash[N].</p>

 <p>Traversal N+1, execute phase: flash access goes to flash[N].</p>

 <p>Traversal N+1, render phase: flash access goes to flash[N+1].</p>

 </blockquote>
