Noticed that "system_env" hangs when executing commands involving printing text, and I needed to do a "<Control-C>" to halt it. I’m uploading two examples. The file test_system_enva.bro calls exit.py and exits on its own. The file test_system_envb.bro calls test.py and does not exit on its own.
Encountered on Linux/Security Onion VM running on VMWare Fusion
The second example doesn't actually hang, it just looks like it hangs due to
the print output.
