Indeed, all the credit goes to Min.

That's the part we use tornado for, so indeed if you wanted to go this
route but run on GAE instead, you could replace our tornado-using code
as indicated in your ascii-diagram above. The code that does this is
mostly in the various modules here:
That directory is the only part of IPython that uses tornado, which is
effectively what you're talking about replacing.
