I put a breakpoint in emacs_close but for some reason it went into
abort instead.

However, Stefan Monnier suggested[0] that this line of python.el may
be the cause:
  (python-send-receive "import emacs; print '_emacs_out ()'")

This is correct.  python-send-receive loops forever waiting for the
"_emacs_out" to be printed, which it isn't because of an
incompatibility with python 3000.
