Actually, in days without continuation (Lua 5.1), LuaJIT has developed
a patch named Coco[1], which make this possible. I do not know whether
the patch works with current Lua release or not.

But, as said in Coco's documentation, this needs machine-specific
features. Lua sticks to ANSI C, which provides no way to switch
stack. So continuation may be the best acceptable way to handle
this kind of yielding.
