I am looking for a way to cleanly stop my service in the event of an error.  
Within the worker thread, if an unrecoverable error is caught, I would like
to stop my service.  Exiting the worker thread doesn't seem to do it.  Using
the SCM to stop the service doesn't feel right.  Am I missing something?  My
service looks like (unrunnable example code below):

public partial class MyService : ServiceBase
{
protected override void OnStart(string[] args)
{
    ListenerWorkerThread = new Thread(new ThreadStart(PortListener));
    ListenerWorkerThread.Start();
}
protected void PortListener()
{
    try
    {
     //do some work
    }
    catch (Exception ex) //some really bad error
    {
       //Write it to the log and stop the service cleanly
    }
}
}
