Describe the bug

this finishes in five seconds

time timeout 5s nix build --store 'daemon?protocol=legacy' $(nix-instantiate --expr 'with import <nixpkgs> {}; runCommand "foo" {} "echo started; sleep inf"')'^*'

this does not

time timeout 5s nix build --store 'daemon?protocol=lix-xp-1' $(nix-instantiate --expr 'with import <nixpkgs> {}; runCommand "foo" {} "echo started; sleep inf"')'^*'

depending on the derivation it may not finish at all, or take a very long time

Expected behavior

they should be the same
