Greg, I never said you couldn't spend time on whatever you want.
You're not even under any obligation to meet milestones, although it's
awesome that you want to.

However, you said you thought the change should be backed out, and
neither Ben, who made the change in the first place, nor I really
understand the problem you're trying to solve (as Ben articulated very
well in his reply). Since part of my role is to prioritize my time
and Ben's, I posted saying, essentially, that I'd like to delay
discussion of reverting the change until after higher priority things
are done.

If delaying the discussion, or the reversion, causes a roadblock for
you, that's a different matter (though one not made clear in your
original post). If it's holding you up, we should talk about it now.

Note that we haven't found that we have to modify client/Makefile.am
much -- whatever inconvenience is going on here, it's apparent only to
you, not to myself or Ben. Maybe it'll be faster if you and Ben talk
on the phone about it?
