148/**
149 * Task structure for asynchronous VM operations.
150 *
151 * Once created, the task structure adds itself as a Console caller. This means:
152 *
153 * 1. The user must check for #rc() before using the created structure
154 * (e.g. passing it as a thread function argument). If #rc() returns a
155 * failure, the Console object may not be used by the task.
156 * 2. On successful initialization, the structure keeps the Console caller
157 * until destruction (to ensure Console remains in the Ready state and won't
158 * be accidentally uninitialized). Forgetting to delete the created task
159 * will lead to Console::uninit() stuck waiting for releasing all added
160 * callers.
161 *
162 * If \a aUsesVMPtr parameter is true, the task structure will also add itself
163 * as a Console::mpUVM caller with the same meaning as above. See
164 * Console::addVMCaller() for more info.
