116/**
117 * Task structure for asynchronous VM operations.
118 *
119 * Once created, the task structure adds itself as a Console caller. This means:
120 *
121 * 1. The user must check for #rc() before using the created structure
122 * (e.g. passing it as a thread function argument). If #rc() returns a
123 * failure, the Console object may not be used by the task (see
124 * Console::addCaller() for more details).
125 * 2. On successful initialization, the structure keeps the Console caller
126 * until destruction (to ensure Console remains in the Ready state and won't
127 * be accidentally uninitialized). Forgetting to delete the created task
128 * will lead to Console::uninit() stuck waiting for releasing all added
129 * callers.
130 *
131 * If \a aUsesVMPtr parameter is true, the task structure will also add itself
132 * as a Console::mpVM caller with the same meaning as above. See
133 * Console::addVMCaller() for more info.
