I haven't boiled this down to a root cause yet, this is a placeholder until I can get a good use case.

Background - I have app I'm exploring Celluloid with https://github.com/copiousfreetime/ghent via JRuby, I updated to JRuby 1.7.3 and now one of my actors appears to be crashing when it attempts to process its mailbox - https://github.com/copiousfreetime/ghent/blob/master/lib/ghent/api_request.rb#L29.

Just an FYI if someone else has any issues with JRuby 1.7.3. I'll dig further into this when I get a chance in a week or so.
