What exactly were you expecting? If you open a terminal window and
start, say, firefox from it, the terminal window will "hang" until you
close firefox - then you get another prompt and can give it some more
input. This is no different. It would be nice if emacs were
multithreaded, but it isn't (at least not yet).

When you say "this" doesn't happen, what do you meant by "this"?  How
does this example compare with the previous example? They look
completely different to me.
