You can read `isInTransientScope` without a lock as long as there can't be any write in another thread, and these writes are forbidden.

Basically we could assert something like:

```
bool isInTransientScope() const {
  assert(!transientAllocator || !getContext()->isMultithreadingEnabled());
   return transientAllocator != nullptr;
}
```
