If I do "opensipsctl ul show", I see those registrations that are supposed to be gone are still in the result, with Expires = "deleted" or "expired" for the next 10+ seconds.

You can see deleted records still kept in memory only when using DB 
persistence - records (even deleted) are kept in mem until DB flush is 
performed again, so that the records are deleted from DB also - so 
maximum to stay is the DB flush interval.
> 2.  I noticed that save() does not update the call-id if everything else (contact, received...) stays the same.  Say a device has been registered the whole time.  A power blip knocked it out for a short while.  The registration in OpenSIPS becomes "expired".  The device is now back online and tries to register with a new call-id before the old reg disappears from OpenSIPS.  What I'm seeing is that the current registration still has the old call-id.  It is causing issues when we use the callid option of registered().

A different call-id means a different registration, so in the scenario 
you mentioned, after the device come back online, a new registration 
will be created for it (the old one will be not touched).
