> It looks like {{skip()}} would skip bytes on data stream. That assures next read is going to be a checksum error. If skip() is not supported, ideally it should throw an exception with clear message.
> Also positional reads ({{read(long position, buf)}}) don't seem to checksum the data. It might be ok, but it is not obvious to users.
