--------------------------------------
Hey Benedict,
I already have code for this. BTW, I don't see option to assign tix to myself.
Can you assign it to me?

> Off-heap memtables (memtable_allocation_type:offheap_objects) introduced by
> CASSANDRA-6694 uses native GCC allocator. Provide an option to use JEMalloc
> allocator (http://www.canonware.com/jemalloc/) which is good to reduce
> fragmentation.
> CASSANDRA-3997 adds below option for off-heap caches and metadata. But it's
> not in effect for off-heap memtables. Should be use the same option or add
> another?
> memory_allocator: JEMallocAllocator
