This bug is reproducible on Mac OS X 10.6 with latest Mono 2.10.2. After
executing next command:

launchctl stop your.deamon.id.string

CPU usage of daemon process rises to 100% and after 20 seconds (default
timeout) it is killed by launchd. This bug is mentioned on several forums, for
example:

http://go-mono.com/forums/#nabble-td3341154
http://stackoverflow.com/questions/3290247/mono-service2-loops-on-exit-running-on-mac-osx-10-5

For now I use next workaround:

protected override void OnStop()
{
  Thread thread = new Thread(CheckExit);
  thread.IsBackground = true;
  thread.Start();
}

private static void CheckExit()
{
  System.Threading.Thread.Sleep(1000);
  Process process = Process.GetCurrentProcess();
  process.Kill();
}

Which simply waits for 1 second after finishing processing of stop signal and
kills itself - very bad workaround, but it avoids 20 seconds wasting of 100%
CPU resources.
