142	* Task structure for asynchronous VM operations.
143	*
144	* Once created, the task structure adds itself as a Console caller. This means:
145	*
146	* 1. The user must check for #rc() before using the created structure
147	* (e.g. passing it as a thread function argument). If #rc() returns a
148	* failure, the Console object may not be used by the task.
149	* 2. On successful initialization, the structure keeps the Console caller
150	* until destruction (to ensure Console remains in the Ready state and won't
151	* be accidentally uninitialized). Forgetting to delete the created task
152	* will lead to Console::uninit() stuck waiting for releasing all added
153	* callers.
154	*
155	* If \a aUsesVMPtr parameter is true, the task structure will also add itself
156	* as a Console::mpUVM caller with the same meaning as above. See
157	* Console::addVMCaller() for more info.
