Assuming I am going to allow only 2 users the log is full and C should not be allowed but as B did a bum-rush out of the application C is technically allowed to log in.

You're right. Perhaps we can also test against some most commonly used database file (or some other file the application opens right away) using WhoHasFile routine. However, this idea just came to my mind, so I'm not sure it would work.

There could be procedure running periodically to clean up "dead" users, but it's still not a good solution.

I guess I don't see a solution from the top of my head.
