How to detect interruption in a plugin

[basarat]

The following don't get called with option spawn:false:

process.on('SIGINT', function () {
    console.log('interrupted!!!!!!!!!!!!'.red);
    process.exit();
});

process.on('exit', function (code) {
    console.log('exit!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!'.red);
});

basically if I call done from an async task after grunt-contrib-watch thinks its completed it, then grunt-contrib-watch gets completed and exits.

Workaround:

// If grunt-contrib-watch is the current task do not call done
            if (grunt.task.current && grunt.task.current.name == 'watch') {
                return;
            }

Not ideal. I need some way of knowing if someone called : https://github.com/gruntjs/grunt/blob/155609c39928d530f13d8e4581a27455be995792/lib/util/task.js#L201 on my behalf

spawn: false runs everything in the same process context. process.on('exit') is only going to be called when the process exits. The watch is designed to never exit, so it is expected to never be called.

If you need to know when a process exits then you'll need to spawn processes.
