        Ruby Memory Vector: Allow more than 4GB of memory
        The memory size variable was a 32-bit int. This meant that the size of 
the
        memory was limited to 4GB. This patch changes the type of the variable 
to
        64-bit to support larger memory sizes. Thanks to Raghuraman 
Balasubramanian
        for bringing this to notice.
