includes neat new features:
- Inter-actor stack traces: previously Celluloid’s stack traces were
to interpret because they stopped at the boundaries between actors. Now
Celluloid can trace calls across actors, assembling calls into a single
stack trace that shows where calls between actors were made.
- Celluloid::Condition: ConditionVariable-like signaling between tasks
within the same actor or between actors
Another important change answers an often raised complaint: Celluloid
starts some default services and installs an exit handler which does a
clean shutdown and prints a small report. While I feel these features

getting started found this annoying.

you only do:
