stack frames

[Roland Silver]

I have some questions about stack frames -- or rather, the stack on 
which stack frames are allocated -- call it the "F-stack".

1. How many bytes are allocated to the F-stack when an app is launched?

2. How can I specify that allocation?

3. What happens if that stack is overpushed?

4. Is there protection against overpushing the F-stack?

I'd greatly appreciate anyone answering some or all of these 
questions, with a Cc to me at <rollo@kitcarson.net>.
