I submitted a review for Flume 2875 a week ago. I have updated it a few times since then, the last being on Feb 5. No one has apparently looked at the Review. As you might know, I am not a fan of RTC for the exact reason that it slows everything down with no assurance of any value being added.
The policy on the wiki says nothing about review requests that are ignored. I would propose that if a review gets no feedback within 72 hours then the committer is free to commit their change. FWIW, I plan to do exactly that tonight or tomorrow as time permits. Ralph
