Not sure what locking a thread is but maybe you just wanted to ask for a mutex. You can use [sys.thread.Mutex - Haxe development API](https://api.haxe.org/v/development/sys/thread/Mutex.html) in Haxe 4, in Haxe 3 you still have to use target-specific APIs like [cpp.vm.Mutex - Haxe 4.2.1 API](https://api.haxe.org/cpp/vm/Mutex.html). If it’s a semaphore you’re after you’re sadly out of luck.
