Well, maybe I am wrong, but Zope really drops the connections -- I had tested 
it specially. Zope 2.6.2 and 2.7.b2 doing this -- I can show you. I had 
tested it with Oracle. Just turn off the reconnect in __setstate__ of the and you will see it. Maybe it should not, but practically it 
does. The same, when you put the connection class to the session. Strange, 
that connections sometimes are dropped after few seconds or minutes, if you 
do nothing. After you login several times with the same user, then 
connections are not dropped because of cache and threads are keeping the 
volatile attribute. But they are not dropped even you want they could be 
dropped, untill "Flush Cache" is pressed on. But keep in mind, that usually 
"Flush Cache" could not help either.
