If the administrator decides to add the SGE_Helper_Service (for Windows GUI
jobs) to a running Windows execution host and uses the "inst_sge -winupdate"
function for it, after installing the Service, the install script starts a new
execd instance, even if the old one is already running.

Either it should first stop the running one, or it should detect there is
already one running and not start the new one. This decision depends on if it is
necessary to restart the execd after installing the SGE_Helper_Service.
