>             Project: Ignite
>          Issue Type: Bug
>      Security Level: Public(Viewable by anyone) 
>    Affects Versions: 2.3
>            Reporter: Alexey Goncharuk

>             Fix For: 2.4

>
> We have the following pattern in PageMemoryImpl#stop():
> {code}
> volatile boolean closed;
> ...
> closed = true;
> writeLock.lock();
> writeLock.unlock();
> {code}
> An empty lock/unlock pair can be eliminated, so the code must be changed and the flag should be moved to the segment class.
