Hi Steve, The backup thread only holds the lock long enough to create an in-memory representation of the data. It writes to disk on it's own time after it has released the lock, so this is not an issue.
If you're saying what I think you are, then a single lock is actually better for performance than multiple locks so long as one avoids waiting for other resources like I/O. -Dan -- http://mail.python.org/mailman/listinfo/python-list
