If you skip the Github model and keep contributor branches, then you
should be able to rebase yourself just before merging, and use
"git merge --ff ..." to make sure it's fast-forward. But as I pointed
out, there may be something attractive productivity-wise about the
Github model. I like the extra channel of communication it brings.

Yes, that's the intention. The point is that it may take time to get
wide implementation across compilers and architectures, so we would
build on all the porting work which has gone into libatomic_ops in the
meantime. Once the calls are converted in bdwgc, we could check for
atomics.h and fall-back to the libatomic_ops. My reference was the C1X
update at http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1349.htm
