[Zope] Python, persistent objects and caching

[Soren Roug]

Hi,

I'm developing a Python-based product that uses persistent objects in
ZODB to store its configuration. No surprises there, but my product is
also using volatile attributes to do a bit of caching of its own. The
thing is, when ZODB takes a sweep every 60 seconds to flush it's own
cache it will quite often flush my product as well, essentially
rendering my 15 minute caching ineffective.

If there a way I can prevent this from happening?
