  "message": "Add a `queue_destroy` API.\n\nThis new API destroys a queue, waking up all threads waiting to produce\nor consume, and making them fail to acquire the lock, before\ndeallocating the underlying allocation. This is particularly useful when\ndestroying a message queue from an error handler.\n\nThis requires to add a destruction mode to the high bits lock class,\nwhich reduces the maximum size of the queue from 512MiB to 256MiB.\n\nThis also requires to revise our approach to the `buffer` pointer in the\nqueue handle. Since we restrict its bounds in `queue_create`, it cannot\nbe used to free the queue. Revise this by restricting the bounds in\n`queue_make_receive_handle` and `queue_make_send_handle` instead.  From\nan adversarial perspective, this is fine: anyone who has access to the\nunrestricted queue can arbitrarily write to `consumer` and `producer`\nanyways. Unfortunately it is a downgrade in terms of catching accidental\noverflows of the queue `buffer` when using the unrestricted queue.\n\nSigned-off-by: Hugo Lefeuvre \u003chugo.lefeuvre@scisemi.com\u003e\n",
