I don't see why this is needed --- isn't it dominated by a begin-end sequence?

It isn't really needed in the sense that it should be unreachable. It is needed if we exit normally from the loop though so I included it for completeness (admittedly it won't help if one return from the loop).
It isn't dominated by a begin-end since the leave from the try-catch implicitly reset the defer_signal counter.
* Add a SIGINT dead time after a force throw
Fixes Jeff's issue in #17706
* Make the eval and print loop sigatomic to avoid sigint being delivered
outside `try`-`catch` blocks.

Can you summarize the behavioral upshot of this change? |

Brillant. |
