Hello,

Finally , i have read the following, and it says this:

"Starvation freedom is desirable, but not essential
—practical locks: many permit starvation, although it is unlikely to occur"

read here:

So as you have just read , starvation is unlikely to occur with spinlock 
eith backoff, so the probability is
very low that starvation occurs, so i will return back to the Spinlock 
with exponential backoff inside my SemaMonitor and SemaCondvar cause it 
has a decent performance.



Thank you,
Amine Moulay Ramdane.
