<!-- Thank you for filing an issue to help us improve Dune! --> ## Expected Behavior Running `dune coq top --no-build ...` should not fail if there is a concurrently running `dune build` command. ## Actual Behavior You get: `Error: A running dune instance has locked the build directory`. Is there anything we can do to fix this? Or does `dune coq top --no-build ...` possibly need to build stuff?
