coffee script cakefile task not finishing

Question

I have the following cakefile task to run selenium tests which runs successfully and gets to the end of the tests but doesn't exit.

muffin = require 'muffin'
wrench = require 'wrench'
http   = require 'http'
fs     = require 'fs'
spawn  = require('child_process').spawn
exec   = require('child_process').exec

task 'selenium', 'run selenium tests', (options) ->
    sel = require './test/selenium'
    app = spawn 'node', ['app.js']
    app.stdout.on 'data', (data) ->
        if /listening on port/.test data
            selenium = spawn 'selenium'
            selenium.stdout.on 'data', (data) ->
                console.log 'stdout: ' + data
                if /Started.*jetty.Server/.test data
                    sel.run ->
                        app.stdin.end()
                        selenium.stdin.end()
                        console.log 'completed Selenium Tests'

Is there a way I can tell the task to finish? I get the 'completed Selenium Tests' logged in the console.

Trevor Burnham, pointed my in the right direction. But the underlying issue was that the selenium child process i was spawning was a shell script running a java process. So basically when calling app.kill() it was killing the shell script but not the underlying java process.

Thanks for the help.
