This is true - if this were a normal persistent object. But that is  
only true with a few user folder implementations, like the bog- 
standard Zope user folder.

For most user folder implementations the user object cannot counted  
as being persistent because it is assembled on the fly using data  
from external sources (RDBMS, LDAP, etc). It gets used once (or a few  
times if it bis cached internally for speeed) and then thrown away.

Basically, the expectation you mention is unrealistic for most user  
folders out there.
