<p class="para">
Session data is usually stored after your script terminated without the
need to call <span class="function"><strong>session_write_close()</strong></span>, but as session data
is locked to prevent concurrent writes only one script may operate on a
session at any time. When using framesets together with sessions you will
experience the frames loading one by one due to this locking. You can
reduce the time needed to load all the frames by ending the session as
soon as all changes to session variables are done.
