[Zope] setting session "data object timeout"

[fred@ontosys.com]

I'm working on an application that uses the default session management
objects in Zope 2.5.1.  I'd like transient session data to last so
that it does not disappear before the user closes/deletes the browser
window maintaining the session cookie.

I'm considering setting the "Data object timeout" parameter to zero in
/temp_folder/session_data.  But when will the session data objects
ever be deleted in that case?  Are they only going to disappear when
when Zope restarts?  If so, should I instead set the timeout parameter
to some large value such as 1440?
