Summary: CGIHTTPServer fix for Windows

Initial Comment:
CGIHTTPServer.py in the Python 2.1 library needs two 
changes to the popen2 section in order to support 
binary data and to avoid buffering problems under 
Windows. The complete code block is shown at the end 
of this message. The two changed lines are:
cmdline = "%s -u %s" % (interp, cmdline)
fi, fo = os.popen2(cmdline, 'b')

I've tested this under Windows 2000 Pro and binary 
file uploads now work, however more extensive tests 
should probably be done.

It appears there is another socket-related problem 
and/or end-of-line conversion error that occurs when 
using Internet Explorer 5.x and BASEHTTPServer with 
CGIHTTPServer on the same machine. I'm still 
investigating that issue.

Finally, I have done a small rewrite of 
CGIHTTPServer.py to simplify subclassing it to support 
running CGIs in any or all directories and using other 
file extensions such as .cgi. The maintainer for the 
current file should email me about the changes to see 
whether they want to update the official library file. 
I didn't post it here since it needs more tweaking
