There are no plans to remove AllocateHeapAt functionality I am aware of. 
It is also much less intrusive than AllocateOldGenAt as you can see from 
this huge change, and actually works as far as I know :)

AllocateHeapAt is also an easy way to get huge pages for your heap via 
HugeTLBFS without reserving them exclusively upfront, or putting the 
entire java heap onto NVDIMMs (afaiu, but you might notice that I'm no 
real expert in this).

Thanks,
   Thomas
