That is why I wouldn't recommend using it unless you specifically know what you are getting into...

There are plenty of time-wasting things that I would never sit around watching which I am more than happy to leave running overnight.

zopflipng is definitely not something to use in a generic automation routine.

I am happy to set it running on a directory overnight and reopen books to update the images, if it means space reduction -- even minor. It doesn't really cost anything (except preparation) and overly large books make me sad.
