	Okay. I'm not sure why the user isn't getting a mid-air. Are you not
updating delta_ts? It's theoretically possible for Bugzilla to have
conflicting transactions that both go through and both happen after the
mid-air check, but the probability is extremely small. Other than that,
as long as you're updating delta_ts, there's no way for two changes to
happen without mid-airs unless both of them are API clients who aren't
respecting the mid-air protection.
