> Eviction from offheap to swap is done using listener on GridUnsafeMap. Notification of
this listener happens when value is already deleted from offheap and lock is released (GridUnsafeMap
line 860). So "get" operation on cache can miss the value while it is in between.
> Need to:
> 1) Review this code piece;
> 2) Create a test reproducing the issue;
> 3) Fix it.
