bug: setIntervals do not clear on ctrl+c

[Qainguin]

To reproduce, use the following Nodepod boot config, run node logger in the shell, then press Ctrl+C. Redo this a few times and you will see that the setIntervals never clear when Ctrl+C is pressed.

pod = await Nodepod.boot({
  workdir: '/home/user',
	files: {
	  '/home/user/logger.js':
		'// uuid-logger.js\n\nsetInterval(() => {\n\tconsole.log(crypto.randomUUID());\n}, 1000);'
	}
});
