In the past couple days, we took some changes from upstream Nix daemon
code (7f3b2510d) that change the way --check works. 

I haven't tried it yet, but it seems that it will allow you to keep
build logs if you pass --keep-failed and if the build differs from the
previous iterations. If it does not differ, then it shouldn't matter :)
