Overview

Public: A simplified implementation of [::Concurrent::ThreadLocalVar](github.com/ruby-concurrency/concurrent-ruby/blob/7dc6eb04142f008ffa79a59c125669c6fcbb85a8/lib/concurrent-ruby/concurrent/atomic/thread_local_var.rb)

Why not just use concurrent-ruby? We wanted to minimize external dependencies to avoid conflicts with gems already installed with github/github.
