DO NOT MERGE YET!!!
Are you using these `export OUT=%s` and `export ERR=%s` anywhere? 

I'd vote to totally remove these variables. If we need to redirect the stdout and stderr to a file we can do that using python, which seems much cleaner than asking any sub shells to intentionally use the OUT/ERR variables to redirect themselves to a file. Also, if we redirect output using python, we have the option to send the output to *both* the console and to a log file using a parameter like `--log-level`
