setjmp() / longjmp() already are nasty stack-adjusting hackery. The
stack-copying would be simple approach that would just work and could
quickly be implemented.
Compilers that care for performance could (if enough people use the
continuations to make it worth) instead handle them in a special way
(like e.g. code is directly being generated for memcpy() instead of a
functionc all). There are many variants of the stack-copying hackery
that are much more efficient than a simple unconditional full copy (see
e.g. "Implementation Strategies for First-Class Continuations" by
Clinger et alii).
