Hm. I think I'll try a first version without an additional register flags argument. And here's why: I'm not sure it buys us a lot especially if we're giving up on making this convenient for seccomp anyway. And with that out of the way (at least for the moment) I would really like to make this interface consistent. But we can revisit this when I have the code. Christian
