    80 /**
    81  *  Task structure for asynchronous VM operations.
    82  *
    83  *  Once created, the task structure adds itself as a Console caller.
    84  *  This means:
    85  *
    86  *  1. The user must check for #rc() before using the created structure
    87  *     (e.g. passing it as a thread function argument). If #rc() returns a
    88  *     failure, the Console object may not be used by the task (see
    89        Console::addCaller() for more details).
    90  *  2. On successful initialization, the structure keeps the Console caller
    91  *     until destruction (to ensure Console remains in the Ready state and won't
    92  *     be accidentially uninitialized). Forgetting to delete the created task
    93  *     will lead to Console::uninit() stuck waiting for releasing all added
    94  *     callers.
    95  *
    96  *  If \a aUsesVMPtr parameter is true, the task structure will also add itself
    97  *  as a Console::mpVM caller with the same meaning as above. See
    98  *  Console::addVMCaller() for more info.
     43
     44/*
     45 * VC++ 8 / amd64 has some serious trouble with this function.
