//! Implementation of [Lamport's bakery algorithm][bakery]. This is somewhat
//! interesting, because it's a mutex which can be implemented even if the
//! target only has atomic load/store, and no CAS (in principal it can be even
//! more general than this).
//!
//! [bakery]: https://en.wikipedia.org/wiki/Lamport%27s_bakery_algorithm
//!
//! Major caveat: This is not tested, and this algo is no longer appropriate
//! for modern code. Some variations of it can be useful in a thread pool, but
//! it's mostly useful to understand the concepts.

//! Sketch of a alternative way to implement the backend of `zeroize` (the part
//! that does memory zeroing).
//!
//! It should be:
//!
//! - More efficient, possibly much more (for byte arrays), as it can zero in
//!   the most efficient way available, rather than e.g. being forced to
//!   perform element-at-a-time writes (where "element" often is "byte").
//! - Still guaranteed even in the face of aggressive compiler optimizations
//!   as the semantics of volatile loads forbid the compiler from being able
