Vladimir Ozerov resolved IGNITE-2316.
-------------------------------------
    Resolution: Won't Fix

Profiling didn't show any benefit even in local benchmarks. Hence, closing as 
"Won't fix".

Implementation is attached. May be we will back to it later.

> 1) GridStripedSpinBusyLock is not striped properly at the moment - produced 
> AtomicIntegers are located too close to each other to produce considerable 
> amount of false-shares. To fix it, int state of each lock should be padded 
> with dummy values. This will give significant throughput increase.
> 2) Then GridSpingBusyLock must be replaced with GridStripedSpinBusyLock all 
> over the project.
