I knew io.popen is sometimes weird on Linux, but I didn't know it would create a deadlock :/ The command you're trying to execute, does it terminate quickly afterwards, or will it always be active? If it's always active perhaps try to put a "&" after it. (<whatever command> &). In windows try putting "start /b" in front (start /b <whatever command>)
