Calling ph.exit() doesn't terminate spawned process

[ryanone]

Hi, has anyone else encountered this issue? I spawn one or more child processes (ie. PhantomJS instances). After opening up whatever web pages I need to open up, I naturally want to call exit(). However, this doesn't kill/terminate the child processes, and so I'm left with a bunch of orphans.

I've found what hopes to be a fix. Inside of node-phantom.js, we have a proxy variable at the bottom, which is an object with an exit() method. Right now, all it does is call request(). If we add a call to phantom.exit('SIGTERM'), that seems to do the trick.

I can send a pull request if you'd like.

Thanks!
