<para>
Session data is usually stored after your script terminated
without the need to call <function>session_end</function>, but as
session data is locked to prevend 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
laod all the frames by ending the session as soon as all changes
to session variables are done.

Read in session data without locking the session data. Changing
