Who said "overwrite"? The stack would just have been appropriately bigger
(that's what i meant for memory waste). If MiNT has 8k stack, the user
stack space bigger by 8k would satisfy both user process and the system.

Anyways, the reality is we have separate stacks and I don't think we
should discuss such facts ("there's no argument agains a fact" as old
proverb says).
