No, cygwin won't provide POSIX process features, you need to use something that is not Windows. As others say, use a VM. Unfortunately the hard truth with PHP (and many other languages) is that if you're trying to use Windows as a development environment, you're already starting off at a significant disadvantage. If Windows provided equivalent features in its process model, I'd use them, but AFAIK, it doesn't/can't.

I use Ubuntu on my personal computer and for my side projects, but I'm stuck using Windows at work. In any case, I don't develop in PHP so the question was academic.
