  I've reimplemented popen using calldll and the bare Win32 API. Its
available from
http://www.scintilla.org/piper.zip
   The zip file contains Sam Rushing's calldll.pyd which provides access to
Win32, piper.py which implements a PipedCommand class which is roughly
equivalent to popen, and some test/example scaffolding. There is no popen2
or popen3 equivalent included although it shouldn't be too hard to implement
them. The exit status is available and the source can be modified to access
other information if needed.

   Its been tested on both Windows 95 and Windows 2000 and is based on C++
code that has been published and working for 18 months although the
translation to Python was done today. So there may be some bugs in the
translation.
