84/**
85 * Task structure for asynchronous VM operations.
86 *
87 * Once created, the task structure adds itself as a Console caller.
88 * This means:
89 *
90 * 1. The user must check for #rc() before using the created structure
91 * (e.g. passing it as a thread function argument). If #rc() returns a
92 * failure, the Console object may not be used by the task (see
93 Console::addCaller() for more details).
94 * 2. On successful initialization, the structure keeps the Console caller
95 * until destruction (to ensure Console remains in the Ready state and won't
96 * be accidentially uninitialized). Forgetting to delete the created task
97 * will lead to Console::uninit() stuck waiting for releasing all added
98 * callers.
99 *
100 * If \a aUsesVMPtr parameter is true, the task structure will also add itself
101 * as a Console::mpVM caller with the same meaning as above. See
102 * Console::addVMCaller() for more info.
