- libgcc's unwinder machinery should be used instead of backtrace()

This is probably true, but it may be slower.

- for security/classloader/accessibility checks, we should only walk the stack
as far as needed to complete the check, not the entire stack

I don't understand this.  We don't walk the entire stack at the moment.
