Title: "forever start" hangs with node 0.11.9

node.js documentation states that unref() is necessary to release the parent but the example is for "ignore"

when the stdio type is 'ipc', additional listeners are setup that keep references to the child and prevent the exit of the parent process. http://nodejs.org/api/child_process.html#child_process_child_disconnect
