popen3 on windows and interactive subprocesses

[Brian Sturk]

I have a script that is run from within the editor vim.  It uses 
popen2.popen3 to run cmd.exe.  I then grab stdout and submit commands
to it via stdin. It works pretty well right now except for one thing.
When I spawn an *interactive* process, like ftp or cleartool I no longer
see anything on stdout after it's launched. Is this possibly because
the app is writing directly to the win32 console?  Any help/ideas greatly
appreciated.

The script, for those curious vim users, is located here:
