how to resolve collisions

How do wikis resolve collisions (simultaneous updates with partially overlapping changes) if they don't utilize a checkin/checkout mechanism as CVS does?

Optimistic locking.

It's a great euphemism for no locking at all. Instead the application (wiki) detects whether the data I edited and am now saving has been modified by someone else since I started editing it. Very easy to implement with a "Last Modified" timestamp field in each database row.
