      Checksum::gen computes a checksum for a given buffer by casting the content of the buffer into 64-bit numbers, 8 bytes at a time. The casts and subsequent operations yield incorrect results on a big-endian system. A simple fix would be to wrap the buffer in a ConstDataCursor and read the 64-bit numbers in little-endian order.
