/**
 *  daemon start-up routines
 *  -----------------------
 *  upon successful return from dsr_init(),
 *  an LPC-based daemon will have entered its
 *  main service loop in a dedicated thread,
 *  having already established an internal
 *  connection.
 *
 *  remarks
 *  -------
 *  1) in the larger-scale midipix project, three
 *     different daemons are initialized using the
 *     below api, namely the optional tty server,
 *     the optional virtual mount server, and the
 *     posix system call layer internal daemon.
 *
 *  2) the initialization routines make use of two
 *     events: a 'damon-is-ready' event, and an
 *     'internal-client-is-ready' event.  if these
 *     events are not provided by the application
 *     then they will be created by this library,
 *     in which case each of the two handles may
 *     optionally be saved to a caller-provided
 *     address.
 *
 *  3) the dedicated thread of a well-designed
 *     daemon should be able to use a stack that
 *     is relatively very small; to fine-tune
 *     the stack size of the daemon's dedicated
 *     thread, use the appropriate members of
 *     the nt_daemon_params structure.
