Maybe same problem as on Darwin, unsure.

Planning to cherry-pick this onto 18.03 as well
(like was done for the Darwin fix).

  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Fits CONTRIBUTING.md.

Maybe same problem as on Darwin, unsure.

Oh, nevermind they seem to be trying to obtain a lock they already have, but aren't using a recursive lock?

Will investigate...

Exploring locking badness fix in #42150 which replaces this if patch looks good. Closing for now.

(EDIT: oops wrong PR number)
