+  if (isRuntimeUninitialized()) {
+    if (threadId == 0) {
+      // Enqueue omp state object for use by another team.
+      int slot = smid() % MAX_SM;
+      omptarget_nvptx_device_simpleState[slot].Enqueue(
+          omptarget_nvptx_simpleThreadPrivateContext);
+      return;
----------------
Again looking at this code: Shouldn't all threads `return`, ie should it be outside of `if (threadId == 0)`?
