+     * By default, io_uring will interrupt a task running in userspace when a
+     * completion event comes in. This is to ensure that completions run in a timely
+     * manner. For a lot of use cases, this is overkill and can cause reduced
+     * performance from both the inter-processor interrupt used to do this, the
+     * kernel/user transition, the needless interruption of the tasks userspace
+     * activities, and reduced batching if completions come in at a rapid rate. Most
+     * applications don't need the forceful interruption, as the events are processed
+     * at any kernel/user transition. The exception are setups where the application
+     * uses multiple threads operating on the same ring, where the application
+     * waiting on completions isn't the one that submitted them. For most other
+     * use cases, setting this flag will improve performance.
