  // This method ensures that the specified process eventually terminates, and
  // then it closes the given process handle.
  // It assumes that the process has already been signalled to exit, and it
  // begins by waiting a small amount of time for it to exit.  If the process
  // does not appear to have exited, then this function starts to become
  // aggressive about ensuring that the process terminates.
  // On Linux this method does not block the calling thread.
  // On OS X this method may block for up to 2 seconds.
  // NOTE: The process handle must have been opened with the PROCESS_TERMINATE
  // and SYNCHRONIZE permissions.
