Pavel Yaskevich commented on CASSANDRA-3271:
--------------------------------------------
bq. If we're rolling our own Memory, why do we need FreeableMemory subclassing
it?
FreeableMemory is already subclassing o.a.c.io.util.Memory.
bq. I guess we might want a Memory object that we don't reference count around.
Although I can't see any benefit there vs just keeping it on-heap.
I don't see it either. But anyway - if we will need that in the future
o.a.c.io.util.Memory can be changed appropriately.
> off-heap cache to use sun.misc.Unsafe instead of JNA
