// This is is basically a multi-consumer single-producer queue, only with the
// twist that we only care about the latest value set. So the GUI thread is the
// setter, and the worker threads are the workers. The workers wait in line on
// the condition variable and when the setter sets a value, a worker is chosen
// to consume it.
//
// The point is that we always want to have one "fresh" worker thread ready to
// work on our latest value. If a newer value is set, then we don't care what
// happens to the old values.
//
// This implementation is mutex-based and is not lock-free. Normally using a
// lock-free data structure makes more sense, but since the GUI thread goes
// through VimL and Python on every keystroke, there's really no point. Those 5
// nanoseconds it takes to lock a mutex are laughably negligible compared to the
// VimL/Python overhead.
