I am not convinced that we have a need for an environment variable for
this case, TBH. It would be enough to make sure that the spawned
worker is paused on its WaitLatch(), with a naptime large enough to
allow the initial transaction to commit, as in the attached. When the
interruption is run, the worker would stop at CHECK_FOR_INTERRUPTS(),
before beginning a new transaction.
