That's what the code on the "concurrency" branch of the Emacs
repository does -- except that (1) it doesn't allow you to create
special asynchronous programs at all, and (2) it is capable of
switching to another ordinary Lisp program when the current one is
waiting for something (e.g., keyboard input or subprocess output), or
explicitly yields to another.
