[AWS] Some questions about Line_Stack_Size

[Thomas Løcke]

The manual has this to say about Line_Stack_Size:

    The HTTP lines stack size. The stack size must be adjusted for
each applications depending on the use of the stack done by the
callback procedures. The default is 1376256.

Now my questions:

    1. How do I best figure out how much stack my callbacks require?
    2. How was the default calculated?
    3. What happens if, for some reason or another, a callback breaks the limit?
