When a file containing source code is modified, I want to reload it using Python's reload() function, then update classes with the new definitions. I have application-level logic to ensure the objects are in a sane-state during update. The only problem I'm having is when I close the connection after an update, I get ConnectionStateError, "Cannot close a connection joined to a transaction". Setting conn._needs_to_join = True appears to fix this, but it's too much of a hack and I have to test it further. There was similar discussion regarding the "reloading product" over a year ago, but this functionality is specific to Zope, which I'm not using. Also, it seems unmaintained and unreliable, and my have been deprecated.
