We are well aware about consolidation!

Our plan is the following:
 a) Stabilize shenandoah/jdk10
----- we are here -----
 b) Pull recent changes from jdk10/hs (or jdk10/jdk10) -- it should be stable now;
 c) Stabilize shenandoah/jdk10 again
 d) Export history from shenandoah/jdk10
 e) Ask ops@ to purge shenandoah/jdk10
 f) Clone consolidated jdk10/jdk10 to shenandoah/jdk10
 g) Import history to shenandoah/jdk10

Do you have a script that could convert changesets against "split" repository to changesets for
"consolidated" one?

Worst-case scenario: we squash all the changesets into one, and apply it as patch.

That would be very useful.
