This particular problem is bugging me quite a bit.  It makes inferior
python mode useless to me.  The behavior for me is this:

emacs -Q
M-x run-python

At this point, emacs hangs at 100% on one CPU.  After C-g I am in a
*Python* Inferior Python buffer.  At this point if I type a python
expression (4, for example), emacs hangs.  I have to type C-g at least 3
times in order to get the return value.  Note the type of messages I get
when typing C-g in "Recent messages" below:
