Computer unresponsive after accidentally pasting a huge clipboard

[karlhorky]

I recently copied a huge piece of JSON into my clipboard (12k characters) and then must have accidentally clicked on the icon in the dock with my touchpad. My computer was unresponsive for 20 minutes as it entered all of this text, not to mention doing weird things like changing settings in programs and such when I tried to hit some keys like ⌘ to try to stop it.

I don't know what the answer is here. Maybe to prevent pasting over a certain number of characters? I guess I could make my own version of the script that does that, but I wanted to ask for feedback on this to see if there's a better solution.

I took a shot at limiting the string length to 250 in #5.

Not 100% happy with this solution though 😒 Any better solutions much appreciated.
