From looking at the code, I think maybe I should have a return

Well, it currently reads:
The return value from filter_cleanup becomes the slave's exit
status.
I guess I can change it to:
The return value from filter_cleanup becomes the slave's exit
status, so make sure filter_cleanup returns an integer suitable for
a process exit status.
I agree it's there. It just seemed easy to gloss over. Perhaps an
example such as return 0 for ok and anything else for an error ;-) Or
even a little mini-stub in an example filter.
