Hello,

Distributed Reader-Writer Mutex have been updated to version 1.02.

I have provided you now with two versions

In the first version i have not used GetCurrectProcessor() but i have used
GetCurrectThreadID() , and i have also provided you with a second
version that scales better, to be able to use the second version please use
the version2 in defines.inc, i have given you a test.pas example for
the first version and test1.pas for the second version, but don't forget to
use version2 inside defines.inc, to use the second version just uncomment
the version2 inside defines.inc and comment version1.

I have also done a cache line alignement in TOmniMREW, this has allowed
Drwlock to scale better.



Thank you,
Amine Moulay Ramdane.
