1882 * Helper method that starts a worker thread that:
1883 * - creates a pipe communication channel using SVCHlpClient;
1884 * - starts an SVC Helper process that will inherit this channel;
1885 * - executes the supplied function by passing it the created SVCHlpClient
1886 * and opened instance to communicate to the Helper process and the given
1887 * Progress object.
1888 *
1889 * The user function is supposed to communicate to the helper process
1890 * using the \a aClient argument to do the requested job and optionally expose
1891 * the progress through the \a aProgress object. The user function should never
1892 * call notifyComplete() on it: this will be done automatically using the
1893 * result code returned by the function.
1894 *
1895 * Before the user function is started, the communication channel passed to
1896 * the \a aClient argument is fully set up, the function should start using
1897 * its write() and read() methods directly.
1898 *
1899 * The \a aVrc parameter of the user function may be used to return an error
1900 * code if it is related to communication errors (for example, returned by
1901 * the SVCHlpClient members when they fail). In this case, the correct error
1902 * message using this value will be reported to the caller. Note that the
1903 * value of \a aVrc is inspected only if the user function itself returns
1904 * success.
1905 *
1906 * If a failure happens anywhere before the user function would be normally
1907 * called, it will be called anyway in special "cleanup only" mode indicated
1908 * by \a aClient, \a aProgress and \aVrc arguments set to NULL. In this mode,
1909 * all the function is supposed to do is to cleanup its aUser argument if
1910 * necessary (it's assumed that the ownership of this argument is passed to
1911 * the user function once #startSVCHelperClient() returns a success, thus
1912 * making it responsible for the cleanup).
1913 *
1914 * After the user function returns, the thread will send the SVCHlpMsg::Null
1915 * message to indicate a process termination.
1916 *
1917 * @param aPrivileged |true| to start the SVC Helper process as a privileged
1918 * user that can perform administrative tasks
1919 * @param aFunc user function to run
1920 * @param aUser argument to the user function
1921 * @param aProgress progress object that will track operation completion
1922 *
1923 * @note aPrivileged is currently ignored (due to some unsolved problems in
1924 * Vista) and the process will be started as a normal (unprivileged)
1925 * process.
