170/**
171 * Task structure for asynchronous VM operations.
172 *
173 * Once created, the task structure adds itself as a Console caller. This means:
174 *
175 * 1. The user must check for #hrc() before using the created structure
176 * (e.g. passing it as a thread function argument). If #hrc() returns a
177 * failure, the Console object may not be used by the task.
178 * 2. On successful initialization, the structure keeps the Console caller
179 * until destruction (to ensure Console remains in the Ready state and won't
180 * be accidentally uninitialized). Forgetting to delete the created task
181 * will lead to Console::uninit() stuck waiting for releasing all added
182 * callers.
183 *
184 * If \a aUsesVMPtr parameter is true, the task structure will also add itself
185 * as a Console::mpUVM caller with the same meaning as above. See
186 * Console::addVMCaller() for more info.
