In ThreadLocalReadAheadBuffer, in the rare case that chunk metadata and file size are out of sync (e.g. bytes erased from the file after chunk metadata is calculated), we’d enter an infinite loop.
The proposed fix is to throw a CorruptBlockException if we’re trying to read past the end of a file, rather than clamping the read.
