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