I think everyone agrees that the more intelligible the code the
better. Renaming methods and abstractions that are confusingly named
is a good idea.

There's not much disagreement about this. We discussed some of these
specifically over lunch today. Choosing the "right" name can be
troublesome. Having identified the right name, actually changing the
code is trivial. The semantics involved are similar to those
described by the (un)interruptible / (un)preemptible annotations, so I
think the plan was to re-name the methods along those lines.
However, even those names a lot of people (me :-) don't find specially
intuitive (but then again, I don't have better suggestions).
So I don't think you need be concerned. Getting these things right
is important and the more eyes that look over it, the better.
