135	* Task structure for asynchronous VM operations.
136	*
137	* Once created, the task structure adds itself as a Console caller. This means:
138	*
139	* 1. The user must check for #rc() before using the created structure
140	* (e.g. passing it as a thread function argument). If #rc() returns a
141	* failure, the Console object may not be used by the task (see
142	* Console::addCaller() for more details).
143	* 2. On successful initialization, the structure keeps the Console caller
144	* until destruction (to ensure Console remains in the Ready state and won't
145	* be accidentally uninitialized). Forgetting to delete the created task
146	* will lead to Console::uninit() stuck waiting for releasing all added
147	* callers.
148	*
149	* If \a aUsesVMPtr parameter is true, the task structure will also add itself
150	* as a Console::mpUVM caller with the same meaning as above. See
151	* Console::addVMCaller() for more info.
