Yeah actually the Lua implementation I mentioned uses a condition variable (not sure about the mutex).
The unbuffered channel would be a good reason to use that scheme. I was thinking of using pipes so Go's select reduces to the select() system call. But I think you can just do both -- it's cheap. Write to a pipe and and notify a condition variable. I'll experiment with it.
