nested popen4

[julian]

Hi all,
I know it's a kind of bizarre question but here I go: I want to
execute an script using popen4. This script executes a command in turn
using popen4 too. The first one throws a 256 exit code.
Any suggestions?
Thanks
J.

Popen4 is gone in 3.0 and I presume deprecated in 2.6, replaced in both
by new subprocess module. Latter might work better for you.
