Fixes: #16170

[tklauser]

@l1b0k could you please rebase your branch and force push again? It looks like Travis CI wasn't triggered by the latest push. Thanks!

@l1b0k It looks like now the old change (deleting the read-lock) is back rather than the fix you pushed before in d0f0be8

The code changed by this PR doesn't affect these, so no need to re-trigger.

Travis CI still didn't trigger despite rebasing the PR and trying to close/reopen. I've ran these tests locally and verified the race is indeed solved. Marking as ready to merge.
