Debug race conditions in my asynchronous code with detailed timing analysis.

<async_code>
{paste problematic async/concurrent code}
</async_code>

<race_symptoms>
{describe intermittent failures and their frequency}
</race_symptoms>

Analyze:
1. All possible execution orderings
2. Shared state access patterns
3. Missing synchronization points
4. Proper locking/coordination mechanisms
5. Test cases to reproduce the race condition
