As the parameters for map read from JavaScript where explicitely set to int only 2GB could be used for either size or offset even on a 64bit system. The type off_t automatically maps to a int32_t on 32 bit systems and int64_t on 64 bit. The original size_t maps to unsigned which would have been more appropriate but NAN does not contain an unsigned type for 64bit.
