remove unused self.name assignment in manager.__init__()

Nice cleanup overall. This is heading in the direction of a nice simplification I think.

I assume including this was an accident. :)

Seems like all of these could be private, no?

Lol. Adding the FIXME is more work than just doing the inlining, no? :)

Nit: This looks like it duplicates 104-110 without the useful logging. Should they use a helper function to share this code? A FIXME would be fine if you agree.

These are all unused as best I can tell. Am I looking at the wrong code? I tried code searching for them and I looked at https://bugs.webkit.org/attachment.cgi?id=150711&action=review for uses of them. Actually, it looks like you delete most of these in that followup patch.

Meh to this comment. :) I'd delete it.

These all appear unused to me.

FIXME s/yield_to_broker/yield_to_caller/ ?
