Hi,

I was thinking if it would be a good idea to zeroize all memory resources on 
system reset and
madvise dontneed them afterwards. This would avoid system reset attacks in case 
the attacker
has only access to the console of a vServer but not on the physical host and it 
would shrink
RSS size of the vServer siginificantly.

BR,
Peter
