101/**
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.
