// Provide a standard ACE service for managing all the services

//
// = DESCRIPTION
// This implementation is very simple. It just handles each
// client request one at a time. Each request is associated
// with a new connection, which is closed when the request is
// processed. In addition, you must be using the singleton
// <ACE_Reactor::instance> in order to trigger reconfigurations.
// This scheme can certainly be improved.
