Subject: [PATCH] Exit if duplicate launch detected (#212)

amendment to the fix for that issue - the prior fix was to just allow two instances to launch

that probably isn't great for the user, so it's better to just terminate if it detects a duplicate launch, and that only happens if two launches happen within the same second so lol
