Technically, I suppose it could have, but that's not what I was referring to.

What I was getting at was that if you allow programs to do marginal things (like modifying messages after they're queued) then you can get into big trouble when you want to change the semantics.

On the Amiga this was more a matter of programs being sloppy with memory allocation, so you couldn't safely switch to a protected mode on later hardware because programs were passing messages around that hadn't been allocated from public memory.

Sorry if I was confusing.
