That sounds good. Thanks.

So, if I understand the proposed workflow correctly, general hotspot
development on the compiler, garbage collectors and runtime, will go on
in the http://hg.openjdk.java.net/jdk7/hotspot-*/hotspot repos, which
will be combined and merged into the
http://hg.openjdk.java.net/jdk7/hotspot/hotspot/ repo by one of the
hotspot gatekeepers. Then when a new "express edition" should be created
a new branch under http://hg.openjdk.java.net/hsx/[xy]/baseline is made
from that. And when the baseline is declared "stable" the fixes there
will be pushed into http://hg.openjdk.java.net/hsx/[xy]/master.
One of these hsx/[xy]/master sources will then be selected to be in
http://hg.openjdk.java.net/jdk7/jdk7/hotspot/ and
http://hg.openjdk.java.net/jdk6/jdk6/hotspot/
