6th paragraph?

The paragraph starts with "This mean that in this code snippet", however, I believe it should read "This means that in this code snippet". (mean -> means)

second last paragraph, starting with

In the explanation of the fence example with three loads and stores, the order of the happens-before relationship was accidentally reversed.

Instead of

"[..], the acquire fence on thread 2 happens-before the release fence on thread 1."

it should say:

"[..], the release fence on thread 1 happens-before the acquire fence on thread 2."

4th paragraph

"we send an 64-bit integer from a spawned thread"

Looking at the example where an AtomicU64 is used I believe the text may have been written as "an unsigned 64-bit", but "an" should have been changed to "a" with the removal of unsigned.

The lock guard

In Chapters 4 and 9, the Sync implementation of the (Mutex)Guard is missing:

unsafe impl<T> Sync for Guard<'_, T> where T: Sync {}

Without this bound on Sync, the Guard could be shared between threads even when T is not Sync.

2nd code block

The assert checks that s != u32::MAX - 2, but it is called when s is even. Given that u32::MAX - 2 is odd, the assert won't fire when the max number of readers is reached.

Note from the Author or Editor:
The != operator should instead be a < operator.

the last paragraph of "The Leakpocalypse" text box

Instead of "Only much later, in Rust 1.63, a new std::thread::scoped function was added" it should say "Only much later, in Rust 1.63, a new std::thread::scope function was added".

The sentence "The arc::new function ..." has an error: "..., initializing both counters at one like before..."

Here 'one' must be 'once'.
