It seems goroutine like process and channels are coming to C++: https://github.com/ahorn/cpp-channel
This is interesting, but you can bring that sort of approach to some other language as well. Here is a simple approach to get it done for Java: http://java.dzone.com/articles/go-style-goroutines-java-and. What is hard to implement without support from the language is the CSP-style channel select, which delivers a lot of the power of channels in Go.
Also, without green threads as in Go there is no way to spawn some hundred thousand threads as in Go. Java will start to get into its knees after some thousand threads already depending on how much resources are available to the machine. You can work around this by having a pool of threads process tasks added to queues where the number of queues can become very large. But when your thread pool has n threads and for an overlapping time window you have n long-runners being executed all other tasks are stuck till the first long runner has finished execution.
Green threads and CSP-style channels is what keeps a lot of people with Go as the rest of the language is almost simplistic. What I would really like to have is D with Go's green threads along with channels and channel select. Some people would now smile mildly, but for today's load on servers there is a real necessity. For example read this article "How We Went from 30 Servers to 2: Go". Link: http://blog.iron.io/2013/03/how-we-went-from-30-servers-to-2-go.html
