If the finish task is called with exit code 143 witch coresponds to SIGT...

I've tried to work with grunt-express-server here: https://github.com/nistormihai/grunt-express-server-test
on ubuntu precise 64
with livereload for node rendering but it seemed that the livereload was reloading the browser 
before the express server started.
I found out that somehow the finish process was triggered by  grunt.util.spawn with the exiting task,
and with the exit code 143 see here: http://stackoverflow.com/questions/4192364/always-app-java-end-with-exit-143-ubuntu

So my fix was just to exit if code 143 was received.
Maybe is not the best approach but I didn't had more time to investigate this thoroughly.
