Can't resolve from resolved state

[jbielick]

This library looks great; I'm excited that it exists. However, I'm running into some issues.

We're on sidekiq 4, so I've included celluloid in the gemfile.

From what i can tell, the symptoms I'm experiencing are similar to #3

My enqueueing code:

    MrDarcy.all_promises do
      contacts.map do |contact|
        Workers::Contacts::Filter.as_promise(contacts.id)
      end
    end.then do |results|
      ...
    end

With a sidekiq -c 20 running.

And once the number of promises created exceeds the active workers in the sidekiq pool, I get the error below sporadically. When enqueueing 1000 promises, the failure rate was roughly 8%.

I haven't poked around much; this could obviously be an incompatibility with the newest version of sidekiq or sidekiq pro/ent, but I wondered if it stood out and could be something simple / related to #3's fix.
