/// LifoSem is a semaphore that wakes its waiters in a manner intended to
/// maximize performance rather than fairness. It should be preferred
/// to a mutex+condvar or POSIX sem_t solution when all of the waiters
/// are equivalent. It is faster than a condvar or sem_t, and it has a
/// shutdown state that might save you a lot of complexity when it comes
/// time to shut down your work pipelines. LifoSem is larger than sem_t,
/// but that is only because it uses padding and alignment to avoid
/// false sharing.
///
/// LifoSem allows multi-post and multi-tryWait, and provides a shutdown
/// state that awakens all waiters. LifoSem is faster than sem_t because
/// it performs exact wakeups, so it often requires fewer system calls.
/// It provides all of the functionality of sem_t except for timed waiting.
/// It is called LifoSem because its wakeup policy is approximately LIFO,
/// rather than the usual FIFO.
///
/// The core semaphore operations provided are:
///
/// -- post() -- if there is a pending waiter, wake it up, otherwise
/// increment the value of the semaphore. If the value of the semaphore
/// is already 2^32-1, does nothing. Compare to sem_post().
///
/// -- post(n) -- equivalent to n calls to post(), but much more efficient.
/// sem_t has no equivalent to this method.
///
/// -- bool tryWait() -- if the semaphore's value is positive, decrements it
/// and returns true, otherwise returns false. Compare to sem_trywait().
///
/// -- uint32_t tryWait(uint32_t n) -- attempts to decrement the semaphore's
/// value by n, returning the amount by which it actually was decremented
/// (a value from 0 to n inclusive). Not atomic. Equivalent to n calls
/// to tryWait(). sem_t has no equivalent to this method.
///
/// -- wait() -- waits until tryWait() can succeed. Compare to sem_wait().
///
/// -- timed wait variants - will wait until timeout. Note when these
/// timeout, the current implementation takes a lock, blocking
/// concurrent pushes and pops. (If timed wait calls are
/// substantial, consider re-working this code to be lock-free).
///
/// LifoSem also has the notion of a shutdown state, in which any calls
/// that would block (or are already blocked) throw ShutdownSemError.
/// Note the difference between a call to wait() and a call to wait()
/// that might block. In the former case tryWait() would succeed, and no
/// isShutdown() check is performed. In the latter case an exception is
/// thrown. This behavior allows a LifoSem controlling work distribution
/// to drain. If you want to immediately stop all waiting on shutdown,
/// you can just check isShutdown() yourself (preferrably wrapped in
/// an UNLIKELY). This fast-stop behavior is easy to add, but difficult
/// to remove if you want the draining behavior, which is why we have
/// chosen the former.
///

/// linearizable.

// Each wait node corresponds to exactly one waiter. Values can flow
// through the semaphore either by going into and out of the head's value,
// or by direct communication from a poster to a waiter. The former path
// is taken when there are no pending waiters, the latter otherwise. The
// general flow of a post is to try to increment the value or pop-and-post
// a wait node. Either of those have the effect of conveying one semaphore
// unit. Waiting is the opposite, either a decrement of the value or
