When we don’t have enough free job slots to run a goal, we put it in the waitForBuildSlot list & unlock its output locks. This will continue from where we left off (tryLocalBuild). However, we need the locks to get reacquired when/if the goal ever restarts. So, we need to send it back through tryToBuild to get reqacquire those locks. I think this bug was introduced in https://github.com/NixOS/nix/pull/4570. It leads to some builds starting without proper locks.
