Hello,

Scalable MLock was updated to version 1.1, now it has
become 100% FIFO fair, and of course it's scalable
and starvation-free.


Author: Amine Moulay Ramdane.

Description:

A node based Lock that is scalable, FIFO fair and starvation-free.

- Discovered by Amine Moulay Ramdane

- This lock is scalable

- It has the same space requirement as the scalable MCS lock

- Doesn't require a local "queue node" to be passed in as a parameter
as is doing the MCS and CLH locks.

- Spins only on local locations on a cache-coherent machine

Please take a look a the test.pas Object Pascal demo inside the zipfile,
compile and run it...
