I was doing macOS ulock stuff, and was linked to Zig's DarwinFutex implementation by @kprotty. There were a few bugs I noticed:
__ulock_wait2actually timeout as au64, notu32(this likely happens to work on at least x86_64 because of how the ABI works, but I can't say about others, and it's still UB either way).__ulock_wait2's timeout is in units of nanoseconds (this would just lead to waking up early which callers have to handle, but still).r? @kprotty
