This is actually a good solution. If, for example, there are two students  
who are there to sign up for exactly the same slot (a conflict) the  
resolution is obtained by their mutual discussion, right there by your  
room. You do not need to invoke Dijkstra or any sort of mutex devices.  
Deadlock is impossible. Some problems are better solved if the computer is  
removed.

If student A absolutely must have the time slot already held by student B,  
it is the responsibility of A to contact B. You, emacs, and the Org crew  
easily relinquish any responsibility.
