Troubles with the python shell under windows

[zaimzet]

For various reasons I'd like to develop python in Emacs under windows. Emacs 
works pretty well in windows, but there are some hiccups with inferior 
processes, like python.

When I enter a statement into the Python prompt that causes an error, the error 
doesn't surface until after the next prompt is entered. I've invoked the 
debugger and done a side-by-side comparison with Emacs under GNU/Linux and the 
point of difference is during the call to process-send-string. In GNU/Linux, 
this results in the error immediately appearing. In windoze nothing shows up 
but another prompt.

It got worse though. I then tried to use TAB to complete at point and Emacs 
completely freezes and I had to kill the process. I take this as a sign that 
something is dreadfully wrong (other than that I'm using windows). I'm guessing 
it sent its call to get the completions, and the response is AWOL.

I was wondering if anyone could help me get to the bottom of this issue.

Keep in mind that this is with native NTEmacs 24.3 and native Python 3. I 
tested it with Cygwin Python 2, and it seems to cooperate, Cygwin Python 3 does 
not. All of my pythons are 64-bit. So it seems there may be an issue with 
Python 3.
