> When a BlockDecoder used via createFileDecoder (ReadStream.pipe(BlockDecoder)) hits a decompression/size error, it emits an error event but does not destroy itself. The upstream file stream can continue reading and feeding data after the error, doing unnecessary I/O/CPU work and possibly emitting multiple errors. BlockDecoder should tear down (destroy) on a fatal error so the pipe unwinds. This touches the hand-rolled finish/push(null) lifecycle in files.js and needs careful testing; split out from AVRO-4287.
