this feature as separate class from `RegionMover` but it lead to lot of code 
duplication. I will try your suggestion today.

   Oh, I thought about implement this `isolate` in the RegionMover itself, just 
as a third operation. This way, I think you could reuse the whole original 
`unload` (or most of it) inside your `isolate` method. Then RegionMover would 
now have three operations: load/unload/isolate. 
   
   In hbck2 we do a lot of "composable" operations, some granular and others 
aggregated.
