> A key component in eliminating the 2GB limit on blocks is creating a proper 
> abstraction for storing more than 2GB.  Currently spark is limited by a 
> reliance on nio ByteBuffer and netty ByteBuf, both of which are limited at 
> 2GB.  This task will introduce the new abstraction and the relevant 
> implementation and utilities, without effecting the existing implementation 
> at all.
