114	* Task structure for asynchronous VM operations.
115	*
116	* Once created, the task structure adds itself as a Console caller. This means:
117	*
118	* 1. The user must check for #rc() before using the created structure
119	* (e.g. passing it as a thread function argument). If #rc() returns a
120	* failure, the Console object may not be used by the task (see
121	* Console::addCaller() for more details).
122	* 2. On successful initialization, the structure keeps the Console caller
123	* until destruction (to ensure Console remains in the Ready state and won't
124	* be accidentally uninitialized). Forgetting to delete the created task
125	* will lead to Console::uninit() stuck waiting for releasing all added
126	* callers.
127	*
128	* If \a aUsesVMPtr parameter is true, the task structure will also add itself
129	* as a Console::mpVM caller with the same meaning as above. See
130	* Console::addVMCaller() for more info.
