102	* Task structure for asynchronous VM operations.
103	*
104	* Once created, the task structure adds itself as a Console caller. This means:
105	*
106	* 1. The user must check for #rc() before using the created structure
107	* (e.g. passing it as a thread function argument). If #rc() returns a
108	* failure, the Console object may not be used by the task (see
109	Console::addCaller() for more details).
110	* 2. On successful initialization, the structure keeps the Console caller
111	* until destruction (to ensure Console remains in the Ready state and won't
112	* be accidentally uninitialized). Forgetting to delete the created task
113	* will lead to Console::uninit() stuck waiting for releasing all added
114	* callers.
115	*
116	* If \a aUsesVMPtr parameter is true, the task structure will also add itself
117	* as a Console::mpVM caller with the same meaning as above. See
118	* Console::addVMCaller() for more info.
