    LongIntegerArrays store 64bit unsigned integers in the range 
    0..16rFFFFFFFFFFFFFFFF.
    In contrast to normal arrays (which store pointers to their elements),
    longIntegerArrays store the values in a dense & compact way. 
    Since the representation fits the underlying C-language systems representation
    of unsigned longlong's, this is also useful to pass bulk data to c primitive code.
    (the system makes certain, that the first longlong is aligned as required)

    [memory requirements:]
        OBJ-HEADER + (size * 8)

    [see also:]
        ByteArray BooleanArray FloatArray DoubleArray Array
        WordArray SignedWordArray IntegerArray SignedIntegerArray
        SignedLongIntegerArray

    [caveat:]
        should probably be renamed to UnsignedInt64Array
