112/**
113 * Task structure for asynchronous VM operations.
114 *
115 * Once created, the task structure adds itself as a Console caller. This means:
116 *
117 * 1. The user must check for #rc() before using the created structure
118 * (e.g. passing it as a thread function argument). If #rc() returns a
119 * failure, the Console object may not be used by the task (see
120 Console::addCaller() for more details).
121 * 2. On successful initialization, the structure keeps the Console caller
122 * until destruction (to ensure Console remains in the Ready state and won't
123 * be accidentally uninitialized). Forgetting to delete the created task
124 * will lead to Console::uninit() stuck waiting for releasing all added
125 * callers.
126 *
127 * If \a aUsesVMPtr parameter is true, the task structure will also add itself
128 * as a Console::mpVM caller with the same meaning as above. See
129 * Console::addVMCaller() for more info.
