Hmm... If the cache update is outside of the lock, more than one thread might have retrieved the sync and try to update the cache concurrently. I think in the current state this will break as multiple thread may pass the `if (InterlockedCompareExchange( &cache->refcount, 0, 0 ))` check successfully.
With a separate lock, we still have to only allow one of the thread to cache its sync, and let the others on the stack.
