> Up on dev list under '[DISCUSSION] Removing the bypass semantic from the
> Coprocessor APIs', we are discussing purge of 'complete'. Unless objection,
> lets purge for beta-1.
> [[email protected]] says the following up on the dev list:
> It would simplify the theory of operation for coprocessors if we can assume
> either the entire chain will complete or one of the coprocessors in the chain
> will throw an exception that not only terminates processing of the rest of
> the chain but also the operation in progress.
> Security coprocessors interrupt processing by throwing an exception, which is
> meant to propagate all the way back to the user.
> I think it's more than fair to ask the same question about 'complete' as we
> did about 'bypass': Does anyone use it? Is it needed?
