That's not the issue.
Does that mean my counter is thread safe?
Morten's product stores the counter's
value in a file on the filesystem, and so it doesn't cause the

since it subclasses Persistent and so gets its own pickle jar.

Ah! this makes more sense, the idea of persistent properties even

even better for some applications ;)
Next time I'll read the whole thread and not the last post in it!

I have a problem with my Data.fs (ZODB). Always, after I change the ZODB

button in the managment screen, it will return to me that the Database was
