// On other platforms, when the underlying native thread is created,
// the thread name is set to the name of the managed thread by another thread.
// However, on OS X and NativeAOT (across all OSes), only the thread itself can set its name.
// However, on Apple platforms and NativeAOT (across all OSes), only the thread itself can set its name.
// Therefore, by this point the native thread is still unnamed as it has not started yet.
