FYI, I disagree that my view is more important in this area since I
have never used the atomic routines.  This is more of a global
maintainer issue (it seems easy to revive them from CVS when needed).
However, Nathan has made a good argument (this is how I translated
everything he wrote on the matter, you might not actually find "the
argument") that we should consider using them in the STL instead of
using the gthr.h mutex abstractions.  It is unclear that I would be
able to do that for 3.1 but I would support someone figuring out how
to do it and study whether it is a win worth supporting.
