It is as if the console ought to be a layer *below* sys.std[in|out|err] that could still talk when those Python channels are closed. At present, we issue the prompt *through* them, using raw_input(">>>").

In my thinking, this lower layer is also necessary so that multiple interpreters may have a sys.std[in|out|err] each, which any one of them could close independently, while others continue to support print() etc..
