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