Yes, sort of. If some visitor acted obnoxiously, like crashed the machine, all the other visitors would be angry, because they didn't want the machine to go down.

Crackers are people who make a practice of breaking computer security, or crashing computers.

So any time you were running a program, the debugger was right there in case anything went wrong. You could start to de-bug instantly.
