bors 56b625be68 Auto merge of #101482 - joboet:netbsd_parker, r=sanxiyn ... Optimize thread parking on NetBSD As the futex syscall is not present in the latest stable release, NetBSD cannot use the efficient thread parker and locks Linux uses. Currently, it therefore relies on a pthread-based parker, consisting of a mutex and semaphore which protect a state variable. NetBSD however has more efficient syscalls available: [`_lwp_park`](https://man.netbsd.org/_lwp_park.2) and [`_lwp_unpark`](https://man.netbsd.org/_lwp_unpark.2). These already provide the exact semantics of `thread::park` and `Thread::unpark`, but work with thread ids. In `std`, this ID is here stored in an atomic state variable, which is also used to optimize cases were the parking token is already available at the time `thread::park` is called. r? `@m-ou-se`		2022-09-11 04:07:17 +00:00
