[Binary semaphore](https://en.wikipedia.org/wiki/Semaphore_(programming))

using [futexes](https://en.wikipedia.org/wiki/Futex). Useful for

saving energy when waiting for new data in lock-free data structures.

The fast path can still be lock-free, only when the consumer has

blocked will you incur the cost of as syscall.
