I must have been sleepy, listing up "cons" vs "drawbacks" ;-) Anyway, the central question is not the size of the job, but the size of the transactions within the job - if the job consists of many transactions, "my" test can be run before every transaction. Having transactions lasting for hours is a very bad thing to do, anyway.
