Yes, I'm pretty sure it is possible.
To unwind the stack, I can use setjmp/longjmp.
To rebuild it, I can use alloca.
This technique is a little more expensive, and
it is a bit tricky, but I think to provide
such an option as a fallback solution.
Still tricky is how to compute stack sizes,
without abusing knowpedge about the setjmp
