Yes, it is ready to land.  There was a fair bit of discussion during the review so I left it after it was accepted in case there were still concerns.  The mutex code was added because it was requested in review.  IIRC, there were concerns about multiple pass managers registering signal handlers.  Since it is for debugging, efficiency of the mutex code is not as important.
