# Description
`config nu/env` used to ignore the frozen wait job status response and
did not add processes to the job table when they were frozen.
This PR refactors the PostWaitCallback used in run_external and allows
frozen processes spawned by `config_.rs` to be added to the job table.
Closes#15389
# User-Facing Changes
`config nu` now respects the job freezing semantics.
# Tests + Formatting
This behavior can be verified by running `config nu` or `config env`,
hitting Ctrl-Z, and then running `job list`.
