Capture file descriptors while running an external program

[jfigueiras]

Hi all!

I have a problem with the module subprocess!
The problem is that the external software that I am running under
subprocess.Popen opens stdin, stdout, stderr, and other file descriptors to
write and read in the hard drive.
I know how to capture stdin, stdout and stderr, what I cannot do is to capture
the other file-descriptors. Is there any way to wrap those non-standard file
descriptors and make them write and read from a specific object that I define?
I know that I can use tmp files to do that, but i would like something running
without tmp files.

Regards...
Joao
