Memory protection clarification.

[Daniel W. <wad...@gm...>]

Hi,

If an application allocates memory from its parent (e.g., from init) - is
this memory capability granted or mapped? Assuming a secure kernel and
IOMMU, how secure is this memory from access by other processes or the root
process?  How is memory clean up after application exit/death?

(Sorry for the newbie questions, I have some catching up to do).
