BTW, do you really need this event loop? It's quite awkward, it would be
much cleaner to call the code directly. Or if you need a work queue for
a certain function call, create a specific workqueue. Don't add a
generic loop like this.
Didn't Bjorn mention something along the lines of that it's not needed
in earlier review?
