> Currently RandomSampleLoader calls skip() on the underlying input stream (BufferedPositionedInputStream)
in its getNext(). The input stream may not actually skip over the amount the RandomSampleLoader
needs in one call. RandomSampleLoader should check the return value from the skip() call and
ensure that skip() is called repeatedly (if necessary) till the needed number of bytes are
skipped.
