concurrently 1.1.0

Concurrently is a concurrency framework for Ruby and mruby based on fibers. With it code can be evaluated independently in its own execution context similar to a thread: hello = concurrently do wait 0.2 # seconds "hello" end world = concurrently do wait 0.1 # seconds "world" end puts "#{hello.await_result} #{world.await_result}"
