⚠️ Deprecated ⚠️

This is deprecated since version 2.8.

Reference counting is done atomically. so g_async_queue_unref() can be used regardless of the @queue's lock.

Decreases the reference count of the asynchronous @queue by 1 and releases the lock. This function must be called while holding the @queue's lock. If the reference count went to 0, the @queue will be destroyed and the memory allocated will be freed.
