What happens when you try to refresh a product?
Nothing. No errors, no refresh.
Then you should look in the SVN repository how the refresh code
changed.
In Zope 2.8, refresh moves all modules starting with
Products.product_to_be_refreshed out of sys.modules
(and into a safe place)

Well, right the session data would be annoying.
But still,
FWIW, the session data problem can be solved with the use of a ZODB
session data container that is not stored in RAM (e.g. an SDC that is
not /temp_folder/session_data), or a reimplentation of a session manager
that uses a relational database or the filesystem.

Refresh always works, at least the explicit refresh (do not know

I'm on 2.7 and yes, the explicit and *very* useful refresh tab in the

I do not remember fondly the old days (2.4, 2.5)
The real effort towards making a better refresh should likely be
spent at the level of the Python interpreter. The dynamic nature of
Python is the thing that allows for a refresh in the first place,
but the implementation of Python object references limits its
usefulness.

Since I never knew the refresh tab was a fragile hack, it always worked

Are you saying that a really good solution for this is in the hands of
