New archives layout is not an improvement

So I see the new website design has just gone live.  While I don't
have much of an opinion on the front page, I do have to say that
I find the new layout of the mail archive display to be near unusable.
It's gone overboard with whitespace to the point where the headers for
a single message fill my screen almost completely.  Scrolling through
a thread of any length is enough to promote carpal tunnel problems,
never mind being able to read it efficiently.

Could we rethink this?
