Here is the reproducer session:

$ nix repl '<nixpkgs>'
Welcome to Nix 2.6.0pre20211217_6e6e998. Type :? for help.

Loading '<nixpkgs>'...
Added 15734 variables.

nix-repl> :b runCommand "foo" {} "sleep 30"
error: interrupted by the user
[1/0/1 built] building foo

nix-repl> :b runCommand "foo" {} "sleep 30"
[1/0/1 built] building foo^C^C^C^C

What happens here:

first I run :b runCommand "foo" {} "sleep 30" and press Ctrl-C 5 seconds after first start. It gets interrupted as expected.
then I run :b runCommand "foo" {} "sleep 30" second time and press Ctrl-C 5 seconds after first start. But it does not stop.

I think it's a regression.
