Monitoring ROR server (thin or mongrel) for resources and availability in WINDOWS and re-spawn

Question

First thing I would like to say is, i know deploying ror applications in windows is not recommended, but in this case i have no choice due to some client restrictions.

I am looking for a tool like Upstart for windows which will moniter my instance of Thin or Mongrel and will 're-spawn' in case of crashes or availability.

Now I looked around quite a bit and most solutions like UpStart, or Passenger server are only available for Unix environments.

Any known tools for windows? and how to use them?

I am also open to any alternative ror servers for windows that can do this automatically like passenger does.

Thanks Shaunak
