The solution...

[aminer]

Hello,

To support the FIFO fairness inside my RWLock i have
found a solution but unfortunatly this solution
is not optimal, cause i have to use two SemaMonitor objects
on the reader side of my RWLock algorithm, but unfortunatly
since my SemaMonitor is using a FIFO queue, the head and tail of this
FIFO queue is always updated by multiple threads so there values has
to move from a L2 cache to L2 cache so this is expensive and
since it's expensive this will make my RWLock not scalable friendly
so i can not use my SemaMonitor in the reader side and since
i can not use my Semamonitor so i think that bringing FIFO fairness
is too hard or even impossible to realize.


That's sad but it's as it's...

So i will let my scalable RWLock as it's now.
