How to kill / abort rails on windows



I have a number of rails servers running on windows as a single
service (written in C#) and would like to terminate all processes when
the service is stopped.

The windows C# way is to use Process.abort(), but it does not seem to
kill all processes.

Another way is to have a controller method perform a Kernel::exit(1)
or an abort(). These terminate the thread, but do not kill the server,
at least not mongrel or webrick.

Maybe the answer is obvious, but I am not really a windows person.

Any ideas?
