* LoAppMem-kHeapMemEnd can be reused as it is.

* No VDSO support.
|

* No MidAppMem region.
|
|
* No additional HeapMem region.
|
|
* HiAppMem contains the stack, loader, shared libraries and heap.
|
|
* Stack on NetBSD/amd64 has prereserved 128MB.
|
|
* Heap grows downwards (top-down).
|
|
* ASLR must be disabled per-process or globally.
