Why are these types not in the standard library?

I'm asking myself, if these are faster why aren't they in libstd? I think read something about platform limitations, but it's not really clear why the standard library has to use platform-specific types. I also saw other people wondering about this, might be worth adding it to the README.

See rust-lang/rfcs#1632.

Great, thanks! I think I'll be using this crate only then. 👍

@alexcrichton mentioned getting this in the nursery. Is that a possibility?

In rust-lang/rust#53127 (comment) it is mentioned that Rust might be more likely to accept parking_lot into the standard library (even rustc uses parking_lot).

It's probably needed to write another RFC to make that change though. I don't think I have the necessary expertise to write it. If someone were interested in this and had some time, it would be nice if they could write it. :)

One more possible concern that didn't get mentioned in the original RFC thread would be whether the code size of parking_lot is bigger than the one of the synchronization primitives in libstd.
