#2076 — Scalable RWLock 3.0

Hello,


Scalable RWLock 3.0 is here...


I have thought all those days about my previous scalable LW_RWLockX,
what i was trying to do is to make the readers side starvation-free
but i have created another problem , the prfevious alorithm favored more 
the readers over the writers and this is not good, so i have decided to 
write another algorithm that solves this problem, i have wrote a 
lightweight EventCount that supports the Signal() and Signal_all() and 
setSignal() and resetSignal(), the setSignal() and resetSignal() are the 
same as the setEvent() and resetEvent() of the Windows event object, and 
i have used a clever algorithm that uses this lightweight EventCount and 
this LW_RWLockX and RWLockX starvation-free and scalable and portable.

Now you will find two algorithms inside the zipfile, one called 
LW_RWLockX that uses spin-wait and that supports the following requirement:

1/ It's starvation-free

2/ It's portable.



I have also provided you with a new algorithm called RWLockX that
uses less CPU resources and that is starvation-free and portable.

Hope you will take a look at my new algorithms inside the zipfile.

Thank you,
