Zombie Child Processes

[sodface]

I'm using xlunch with the desktop and dontquit options and I was seeing a lot of processes with a Z state, a new one added each time I would press an xlunch icon and fire the associated action. I added the below patch and it seems to have fixed it, though I don't really know what I'm doing so there's likely a better approach.
