It's 10 (yes, ten!) new algorithm to do mutual exclusion for the two-thread problem.

They're alternatives to Dekker's or Peterson's protocols. If you don't know what those are then take a look at wikipedia:

All of our 10 algorithms (did I say we had 10 of them?) have a minimum number of stores of 1 to acquire and another store to release the lock. This is something new in the world of 2-thread mutual exclusion:
Why does anyone even care about this stuff?
Well, before you can fly (make wait-free algorithms) you need to walk (make mutual exclusion locks), and some of these algorithms are the basis of reader-writer locks.
... ohhh, and they're all starvation-free :)
