This issue was originally filed by rchandia@google.com

Problem is that FileInputStream assumes the file is seekable.

void main() {

  File stdinFile = new File('/proc/self/fd/0');
  stdinFile.open();
  InputStream stdin = stdinFile.openInputStream();

  void readMore() {
    print(stdin.read(1));
  }

  stdin.dataHandler = readMore;
  readMore();
}

Produces:
An unhandled exception has been thrown
FileIOException: length failed
