POST data is truncated randomly when sent to a python script running on a simple python CGI server on Windows 7 with Python 3.2.3.
The same server and script files run successfully on MAC OSX 10.8 with Python 3.2.3. A similar server (adapted for lower Python version) and the same script file do work fine on Windows 7 with Python 2.7.2. 
Steps to reproduce: Attached zip contains server script, HTML file and Python script, that receives an uploaded file and saves it to disk. Upload an image file and submit the form inside the HTML file to Python script. Repeat form submission multiple times. In more than 50% of test cases, the uploaded file will not be completely available inside the Python script. That means size of the same uploaded file varies with each POST request. Additionally, the Python server will reset the HTTP connection sometimes.

The successful script execution was run under Python 2.7.3 (as of today one of the two as "production version" labeled releases). The initial report's reference to Python 2.7.2 was made by mistake.
May anyone confirm this error behaviour on Python production version 3.2.3 on Windows?

@Alexander apologies for the delay in getting back to you. Who is best placed to look at this issue, I'll admit to knowing squat about cgi?
