    SignedLongIntegerArrays store 64bit signed integers in the range 
    16r-8000000000000000..16r7FFFFFFFFFFFFFFF.
    In contrast to normal arrays (which store pointers to their elements),
    signedLongIntegerArrays store the values in a dense & compact way. 
    Since the representation fits the underlying C-language systems representation
    of signed 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
        LongIntegerArray

    [caveat:]
        should probably be renamed to SignedInt64Array
