Since we now have sys::Env.addShutdownHook it'd be appropriate to leverage this to shutdown any services started by util::AbstractMain.runServices.

Something like:

virtual Int runServices(Service[] services)
{
  Env.cur.addShutdownHook |->|
  {
    services.each |Service s| { s.stop }
    services.each |Service s| { s.uninstall }
  }
  services.each |Service s| { s.install }
  services.each |Service s| { s.start }
  Actor.sleep(Duration.maxVal)
  return 0
}

That's a great idea.
