Does it allocate memory in the C stack as well?  It might be great
if I could use it because the VM would be simplified a bit with it.

On the other hand, if Guile is marking all objects referred from
the C stack, allocating a huge VM stack on the C stack might slow
down GC, while with my current approach, only necessary objects are
actually marked.  I'm not sure how much this might affect.
