After going over the chapter in the ISA pdf the feature doesn't
look as useful as I thought it would be and it's only to prevent
buffer underrun/overrun - no other widespread vector is closed.

Sorry you think I'm trying to trick anyone - that couldn't be
further from the truth but English is not my native language and
I maybe misrepresented the question.
