[Zope] Volatile Properties in ZClasses?

[Tom Schwaller]

Hi,

Take a look at the BannerAd ZClass:
(http://www.zope.org/Members/lalo/BannerFolder)

Updating the "hits"-property when the banner 
is loaded, has the effect, that the
Banner-Object is backuped by the Zope magic,
which is quite annyoing when having a high-traffic 
site. So, how can one generate volatile properties,
which do not get backuped (I tried it whith _hits,
but ZClasses do not likte them ;-) --> Zope Error).

Is there a reason for not allowing _Variables in ZClasses
and how does one solve the Problem in this case
(seems like a generael problem)
