And the technical content of N2798 is the same as N2800, which was
shipped as CD-1 and is now in the ISO balloting process.

CD-1 isn't intended to pass the ballot. Rather, it serves to put the
world on notice that C++0x is feature complete. Essentially a fairly
late beta release. That means that committee work on C++0x futures is
done, except for corrections in response to ballot comments.

It would be very unusual if futures did not make it into the final
C++0x standard, and with little if any change from the current
specification. What change do occur will be mostly tightening up the
specification and tweaking the wording. Few if any new features will
be added.

So we should aim for the Boost threading library to conform to N2800
as closely as we can. It is OK to add extensions, but we shouldn't
leave out features or change existing features, IMO.
