Finally, here's a theoretical solution that I think would be ideal for a lot of people: if we could just ask the RDBMS for its current transaction ID, Zope could keep track of the last transaction ID it knew about, and clear the caches when another process made a change. This solution may yield the highest performance for Zope-centric applications. It would also remove the need for my MD5 hack. ;-)

But would it work for non-transactional storages like file systems?

Nope, unless it's a journaled filesystem and we pulled out the journal log entry number. ;-) Shane
