I also tried with this but it didn't give me anything that I would
want to recommend. Indeed, socket deacativation took place at the
first printing attempt but thereafter the timeout behaviour was
inconsistent. However, IMO, the suggestion and the committed code
from upstream are the best we are going to get for now.

Looking at the debug2 error log lead me to putting

  PreserveJobHistory No

in cupsd.conf. This gives reliable and consistent socket activation
and timing out. How about for you?

Cheers,

Brian.
