Request for comments: small class to create, manage and interact with forks

Hi there

I created a small class to deal with forks, mainly creating, managing
and communicating with forks. But since forks/forking is a bit of a new
topic to me, I’d be happy to get comments on the following bit of code:
forkpool.rb · GitHub (version while posting this:
forkpool.rb · GitHub )

Thanks for your feedback
