In my case, it's very unlikely. Also, I would expect and average of 1 callback per minute, based on what I know about our system. But your point is well taken. Personally, the most I'd wait is 2 seconds: thinking that if I don't get a response after 2 seconds, it's not going to happen. If a person was really concerned about performance then this would not be a good solution. Probably they would want to use dbms_jobs. What would you do?

It does not look like a good thing for performance.
