> In current version of PageMemoryNoStoreImpl, offheap memory is split into equal segments. Quantity of segments is based on MemoryConfiguration#getConcurrencyLevel (or Runtime#availableProcessors, if previous is not set).
> This approach is obsolete. In order to reduce code complexity, segments should be refactored into one memory region.
