The `function --on-job-exit caller` feature allows a command substitution to observe when the parent job exits. This has never worked very well - in particular it is based on job IDs, so a function that observes this will run multiple times. Implement it properly. Do this by having a not-recycled "internal job id". This is only used by psub, but ensure it works properly none-the-less.
