I had the exact same problem yesterday. This is an obvious use case for 
the "bufsize" parameter to os.popen4, except that the Windows 
implementation doesn't accept anything but -1...

The only way I can see out of this is to use win32api to launch the 
process through CreateProcess, then perform asynchronous I/O on its 
stdout using the OVERLAPPED structure in a call to ReadFile... Ugly...
