unsetting several vars saved in a session doesn't work. 
 
eg: 
$HTTP_SESSION_VARS["arr_myfirstarray"] = array("foo","bar"); 
$HTTP_SESSION_VARS["arr_mysecondarray"] = array("foo","bar"); 
 
unset($HTTP_SESSION_VARS["arr_myfirstarray"],$HTTP_SESSION_VARS["arr_mysecondarray"]); 
 
doesn't unset the variables in the session. it does unset them for 
the current script, but doesn't remove them from the SESSION-array 
correctly.

This bug is a kind of design bug, but it's easily fixed.
We need to get rid of PS(vars) and use PS(http_session_vars) as a main session storage. There are some other options, though.

To reporter: You know work around mentioned in the manual, right?

reporter feedback:

do you mean the:
  foreach ($my_array as $element ) {
      unset($element) ;
  }
workaround? or is there any better?

- unset doesn't work as expected if reg_glob is off. setting reg_glob to 'on' makes 
unset working again. only workaround is to dereference if globals are on.
