This assumption was based on that only `hubCallback` sends the `RegistrationPending` message. However, due to that we first enqueue ourselves to a list of registrations, then we send a registration message, we might be registered *earlier* if another downstream kicks off our registration, too, with its own `RegistrationPending`. Then we get the offset earlier than we got the actual upstream callback. The solution is to simply enable pulls once we have both set and don't assume the order between these two events.","created_at":"2016-09-12T12:06:02Z","updated_at":"2016-09-12T12:06:02Z","closed_at":null,"merged_at":null,"merge_commit_sha":null,"assignee":null,"assignees":[],"milestone":null,"commits_url":"https://api.github.com/repos/akka/akka/pulls/21443/commits","review_comments_url":"https://api.github.com/repos/akka/akka/pulls/21443/comments","review_comment_url":"https://api.github.com/repos/akka/akka/pulls/comments{/number}","comments_url":"https://api.github.com/repos/akka/akka/issues/21443/comments","statuses_url":"https://api.github.com/repos/akka/akka/statuses/39f1de87abbf495f6ca600b638425e344d376198","head":{"label":"drewhk:wip-21362-bcasthub-init-race-drewhk","ref":"wip-21362-bcasthub-init-race-drewhk","sha":"39f1de87abbf495f6ca600b638425e344d376198","user":{"login":"drewhk","id":932285,"avatar_url":"https://avatars.githubusercontent.com/u/932285?v=3","gravatar_id":"","url":"https://api.github.com/users/drewhk","html_url":"https://github.com/drewhk","followers_url":"https://api.github.com/users/drewhk/followers","following_url":"https://api.github.com/users/drewhk/following{/other_user}","gists_url":"https://api.github.com/users/drewhk/gists{/gist_id}","starred_url":"https://api.github.com/users/drewhk/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/drewhk/subscriptions","organizations_url":"https://api.github.com/users/drewhk/orgs","repos_url":"https://api.github.com/users/drewhk/repos","events_url":"https://api.github.com/users/drewhk/events{/privacy}","received_events_url":"https://api.github.com/users/drewhk/received_events","type":"User","site_admin":false},"repo":{"id":4322312,"name":"akka","full_name":"drewhk/akka","owner":{"login":"drewhk","id":932285,"avatar_url":"https://avatars.githubusercontent.com/u/932285?v=3","gravatar_id":"","url":"https://api.github.com/users/drewhk","html_url":"https://github.com/drewhk","followers_url":"https://api.github.com/users/drewhk/followers","following_url":"https://api.github.com/users/drewhk/following{/other_user}","gists_url":"https://api.github.com/users/drewhk/gists{/gist_id}","starred_url":"https://api.github.com/users/drewhk/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/drewhk/subscriptions","organizations_url":"https://api.github.com/users/drewhk/orgs","repos_url":"https://api.github.com/users/drewhk/repos","events_url":"https://api.github.com/users/drewhk/events{/privacy}","received_events_url":"https://api.github.com/users/drewhk/received_events","type":"User","site_admin":false},"private":false,"html_url":"https://github.com/drewhk/akka","description":"Akka
