I was assuming atomic increment/decrement operations, in which case I'm not

That's unfortunately too simple. You run into one of two cases:
1. If the job automatically removes the protected attribute when an image
is no longer in use, then you lose the ability to use "protected" on images
that are not in use. I.e., there's no way to say, "nothing is currently
using this i
A simple solution that wouldn’t require modification of glance would be a cron
job
that lists images and snapshots and marks them protected while they are in use.

No, I'm looking to prevent images that are in use from being deleted. "In use"
and "protected" are disjoint sets.

Hi Chris,
Are you looking for the 'protected' attribute? You can mark an image
with 'protected'=True, then the image can't be deleted by accidentally.
