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