Fast Mutex Algorithm
[Lamport, 1986]
In a well-designed system, most of the time only a
single process tries to get into the critical section...
Will be able to do so in a constant number of steps.
When two processes try to get into the critical section?
O(n) steps!

Asynchronous Shared-Memory
Systems
Need to collect information in order to coordinate...
When only few processes participate, reading one by
one is prohibitive ...
