When I try python-send-buffer in the 6/7 nightly build, I get:

    Debugger entered--Lisp error: (error "Variable binding depth
exceeds max-specpdl-size")
      signal(error ("Variable binding depth exceeds max-specpdl-size"))

      python-send-region(1 708)
      python-send-buffer()
      call-interactively(python-send-buffer nil nil)

Is that the failure mode that motivated the comment in python.el prior
to your change?

    ;; `make-temp-file' would be the natural choice for
    ;; implementation.  But it calls `write-region' internally,
    ;; which also needs a temporary file - we would end in an
    ;; infinite loop.
