  * As there can be events, that blocks on waiting for subsequent events,
- * we solve this problem by first copying the event TRBs from the event ring,
- * then asserting EHB and only after, handling the events.

- * IPC notification will create new event handling fibril for us.
+ * we solve this problem by deferring some types of events to separate fibrils.
