> DistCp wraps the {{InputStream}} for each input file it reads in an instance of {{ThrottledInputStream}}.
 This class does not close the wrapped {{InputStream}}.  {{RetriableFileCopyCommand}} guarantees
that the {{ThrottledInputStream}} gets closed, but without closing the underlying wrapped
stream, it still leaks a file handle.
