Yes, of course, catching + reraising an exception is costly. But when an exception is not raised, this is cheap. Usually len() is called for open database.

Hmm. If consider dbm.dumb as separated module, this is perhaps a new feature. But if consider it as an implementation of the dbm protocol, it should conform to other dbm modules, and this is a bugfix. What would you say Nick?
