[Z3-sqlos] recent transaction/threading changes and subscribers

[Joseph Kocherhans]

Ever since the recent transaction changes I've been having problems 
with zope3 hanging when I add/edit sqlos objects. I think I've tracked 
the problem down to subscribers, but I wanted to check to see if anyone 
else is doing something similar.

One of my sqlos objects stores dc metadata. I wrote an adapter to store 
dc metadata in the same table that my sqlobject uses. It simply 
gets/sets attributes on the sqlobject instance. The CreatorAnnotator 
and ModifiedAnnotator are being called infinitely though. Is anyone 
else doing something similar that's working with the HEAD? If I go back 
to r6801 everything works fine.

Thanks,
Joseph
