---------------------------------------

    Attachment: MemoryManagerServiceImplTest.java
                modifiers.patch
                OffHeapLinkedMemoryBuffer.java

Attached is a patch for OffHeapMemoryBuffer and MemoryManagementServiceImpl to turn them to more easily extendable classes.

And a simple test around the class.
