With the branch concept you'd have your own branch. It would depend
on you if you'd be committing CYGWIN DDX specific things to your branch
or to HEAD. The merit of doing this within your own branch is that
you won't be affected by changes others do until you decide you are
ready to. You can merge in HEAD as often as you want - or not if
you want stability for a while.
However the theory behind all this is that ongoing development takes
mostly place in branches while minor fixes go directly into the trunk.

That's not correct. When the release is done the RELEASE-1 branch will
be merged back to CURRENT. How this is done is still open but it will
We should always have a branch from which we cut the release.
Together with scheduling features for release this will give us
a finer control over things and allow people to continue working
on whatever the CURRENT branch will be without interfereing with 
the release.
At release time some tinderboxes should be set up to build the
release branch and beta testers schould be directed to this branch.

So you give the RELEASE branch more time for testing.
You never get sufficient testing when you constantly bring
in stuff from active development.

Right. That's not how we do it.

Different projects have different models. We should be similar to
what others do but if we are convinced that doing something different
has advantages we should not be the slaves of the crowd.

This depends. I assume that still needs to be hammered out. Only
experience can tell what would be the best balance.
