Interesting that you report a problem you have no time for....

This is normal acquisition behaviour...

Modern Zope versions make "aq_inner" available to TTW code.
With such versions, you can use "hasattr(obj.aq_inner.aq_explicit, XXX)"
to check whether "obj" has an unaquired attribute "XXX".

There is also my "hasattr_unacquired" path that provides
"hasattr_unacquired". Its effect is identical to the above
"aq_inner.aq_explicit" magic but it is easier to understand
(for non experts)...
