I also thought about that already.
It's a good idea, but not good enough.  :-(

what's about longjmp(), gotos from nested functions to their surrounding
functions (with a complex calltree inbetween) and (c++) exceptions?

always preserving frame pointers, unrolling the stack frame by frame and
executing this epilogues might be possible - but I don't think that we
really want to go this way..
