Hey, this is not a wasted day, I just learned something!

True.

And I forget to mention the memory swap file. Which would be an easier 
point of access.

True. Though it does slow the attacker down. Which is the ultimate goal 
anyway. There is no encryption system in existance which cannot be 
cracked eventually. You can only strech the time it takes.

Hopefully the cracking time will be longer than the lifetime of the 
sensitivity of the information.

And then some all-knowing C-level PHB will copy the data in clear onto 
his USB key "for convienience" and lose it in a washroom at the strip 
club...
