Does changing Item-Level-Permission trigger ItemUpdated/ItemUpdating in Event Receiver?

Question

First of all: I know that setting item-level-permissions are bad :)

I just wonder: When I created an Event-Receiver that set per-item-Permissions on the ItemAdding-Event:

Will this trigger the ItemUpdating-Event? Or does that only gets triggered when the "pure" item is modified?

The same question to workflows: Do creating/modifying workflows do trigger events on the connected item?

(PS: I know the EventFiringEnabled - Property to prevent this if needed)
