Try using the subprocess module (Python 2.4+) to call your program instead
of os.system. os.system doesn't return an error message, it only returns the
exit code of the subprocess and doesn't give you any of the useful
information that the program may send to it's output and error pipes. With
the subprocess module you can pipe these to your own chlid_stdout and
child_stderr pipes, so you won't have to worry about trying to prevent your
subprocess from writing to stdout and messing up WSGI, etc.:
