So, that means jdk10/hs -> jdk10/jdk10 integration would start happening
*before* repo consolidation, right?

We can use jdk10/hs as the basis for Shenandoah, because we will have to
integrate through that anyway. Too bad jdk10/sandbox does not have jdk10/hs
changes too, it seems:
  http://hg.openjdk.java.net/jdk10/hs/hotspot/rev/ae91ec8b554a
  http://hg.openjdk.java.net/jdk10/sandbox/hotspot/log?rev=ae91ec8b554a

Which means whatever we are doing in sandboxes is not getting exposed to jdk10
mainline work...

Thanks,
