81	* Task structure for asynchronous VM operations.
82	*
83	* Once created, the task structure adds itself as a Console caller.
84	* This means:
85	*
86	* 1. The user must check for #rc() before using the created structure
87	* (e.g. passing it as a thread function argument). If #rc() returns a
88	* failure, the Console object may not be used by the task (see
89	Console::addCaller() for more details).
90	* 2. On successful initialization, the structure keeps the Console caller
91	* until destruction (to ensure Console remains in the Ready state and won't
92	* be accidentially uninitialized). Forgetting to delete the created task
93	* will lead to Console::uninit() stuck waiting for releasing all added
94	* callers.
95	*
96	* If \a aUsesVMPtr parameter is true, the task structure will also add itself
97	* as a Console::mpVM caller with the same meaning as above. See
98	* Console::addVMCaller() for more info.
