FIXMEs in PersistentManagerBase

[Jess Holle]

I have dire need to use PersistentManager, which is experimental at this 
time.

Looking in the source, I note 2 "FIXME" comments -- one of which seems 
to clearly indicate a race condition.  It actually occurs twice (though 
the comment only occurs once) but the code in both cases looks similar to:

           // Swap out all sessions idle longer than maxIdleSwap
           // FIXME: What's preventing us from mangling a session during
           // a request?
           if (maxIdleSwap >= 0) {
               for (int i = 0; i < sessions.length; i++) {
                   StandardSession session = (StandardSession) sessions[i];
                   if (!session.isValid())
                       continue;
                   int timeIdle = // Truncate, do not round up
                       (int) ((timeNow - session.getLastAccessedTime())
   / 1000L);
                   if (timeIdle > maxIdleSwap && timeIdle > minIdleSwap) {
                       if (log.isDebugEnabled())
                           log.debug(sm.getString
                               ("persistentManager.swapMaxIdle",
                                session.getId(), new Integer(timeIdle)));
                       try {
                           swapOut(session);
                       } catch (IOException e) {
                           ;   // This is logged in writeSession()
                       }
                   }
               }
           }
Does anyone have any brilliant ideas/suggestions on how this condition 
should be resolved?  I'm digging around, but my experience with all of 
the pieces involved is rather limited.
