OK.  In that case I suppose I'd like Al to take patches 1-4 of the 5 I
posted most recently (followups to
http://mid.gmane.org/20120425152041.GA751@fieldses.org), probably after
your fixes go in.  I'll resend if necessary after they go in.

(I'm also going ahead and pushing out the rest of my delegation patches,
to be merged for 3.5; that solves most of my delegation problem, leaving
just a race in rename to be closed by those 4 patches.)
