Example (http://hydra.nixos.org/build/2488954):

building path(s) `/nix/store/3ap0adrzz2xz5b6my1pfwrry7j08ar9r-nixos-test-driver'
error: linking `/nix/store/2z2ff51yskqm44kddd10hv4xg2mp40lp-nixos-test-driver.drv.chroot/nix/store/c1n81qbnpp98npc6idkkk4a4z8jnzw1s-upstart-udevtrigger.conf' to `/nix/store/c1n81qbnpp98npc6idkkk4a4z8jnzw1s-upstart-udevtrigger.conf': Operation not permitted

This is due to build.cc:

makeMutable(*i);
link(i->c_str(), ...);
makeImmutable(*i);

If two processes do this at the same time, one may call makeImmutable() before the other has called link().

Don't log from inside the logger
724b7f4 
This deadlocks ProgressBar, e.g.

  # nix run --impure --no-substitute --store '/tmp/nix2?store=/foo' --expr 'derivation { builder = /nix/store/zi90rxslsm4mlr46l2xws1rm94g7pk8p-busybox-1.31.1-x86_64-unknown-linux-musl/bin/busybox; }'

leads to
