libtask [ http://swtch.com/libtask/ ] implements something similar/same; however, it's a coroutine lib and I'm pretty sure it will not work with multiple threads.
However, it does have something like a select() for channels, see the Alt structure and associated methods, IIRC the implementation is fairly simple.
