I envision something like this:
while changes=$(openstack compute server-events --run react-to-status --fields
status id1 id2 id3 id4) ; do
for id_and_status in $changes ; do
id=${id_and_status##:}
status=${id_and_status%%:}
done
done
Not exactly "hard"

It doesn't actually solve a ton of things though. Even if we optimize
it down to the fewest operations, it is still ultimately a DB query and
extra churn in the API service.
