  // this code will result in a maximum of 2 reads of 8192 bytes by calling
  // start() and isRunning().  by the time getOutput() is called the process
  // has terminated so the internal pipes array is already empty. normally
  // the call to start() will not read any data as the process will not have
  // generated output, but this is non-deterministic so we must count it as
  // a possibility.  therefore we need 2 * PipesInterface::CHUNK_SIZE plus
  // another byte which will never be read.
