Hi Andrew,

My proposal would rather be like this:

We have two active trees, hg.openjdk.java.net/jdk8u/jdk8u/ and
hg.openjdk.java.net/jdk8u/jdk8u-dev/. jdk8u-dev is always open to all
contributors, and that's where everyone should push their patches
after maintainer approval.
When the time comes for an update release (e.g. once per quarter),
jdk8u-dev will be copied to jdk8u to build the base for an update release.
jdk8u will be dedicated to testing and stabilization. Only critical bug fixes
may be applied to jdk8u, at the discretion of the maintainers.
[ The fixes done in jdk8u will be merged into jdk8u-dev at regular intervals.]

Isn't that what we want to do?

Best regards
Christoph
