> So, what is going on? 
> Partition had been changed, its pages had been put to checkpoint pages.
> After it partition was evicted, checkpoint started.
> We are allocating a page and because it's already in checkpoint we copy the empty page
to copy it on disk.
> If we restart right now we will read the empty page from disk. Therefore assertion error
would be thrown etc.
