2339 * Helper method that starts a worker thread that:
2340 * - creates a pipe communication channel using SVCHlpClient;
2341 * - starts an SVC Helper process that will inherit this channel;
2342 * - executes the supplied function by passing it the created SVCHlpClient
2343 * and opened instance to communicate to the Helper process and the given
2344 * Progress object.
2345 *
2346 * The user function is supposed to communicate to the helper process
2347 * using the \a aClient argument to do the requested job and optionally expose
2348 * the progress through the \a aProgress object. The user function should never
2349 * call notifyComplete() on it: this will be done automatically using the
2350 * result code returned by the function.
2351 *
2352 * Before the user function is started, the communication channel passed to
2353 * the \a aClient argument is fully set up, the function should start using
2354 * its write() and read() methods directly.
2355 *
2356 * The \a aVrc parameter of the user function may be used to return an error
2357 * code if it is related to communication errors (for example, returned by
2358 * the SVCHlpClient members when they fail). In this case, the correct error
2359 * message using this value will be reported to the caller. Note that the
2360 * value of \a aVrc is inspected only if the user function itself returns
2361 * success.
2362 *
2363 * If a failure happens anywhere before the user function would be normally
2364 * called, it will be called anyway in special "cleanup only" mode indicated
2365 * by \a aClient, \a aProgress and \aVrc arguments set to NULL. In this mode,
2366 * all the function is supposed to do is to cleanup its aUser argument if
2367 * necessary (it's assumed that the ownership of this argument is passed to
2368 * the user function once #startSVCHelperClient() returns a success, thus
2369 * making it responsible for the cleanup).
2370 *
2371 * After the user function returns, the thread will send the SVCHlpMsg::Null
2372 * message to indicate a process termination.
2373 *
2374 * @param aPrivileged |true| to start the SVC Helper process as a privileged
2375 * user that can perform administrative tasks
2376 * @param aFunc user function to run
2377 * @param aUser argument to the user function
2378 * @param aProgress progress object that will track operation completion
2379 *
2380 * @note aPrivileged is currently ignored (due to some unsolved problems in
2381 * Vista) and the process will be started as a normal (unprivileged)
2382 * process.
