Getting the GCRoot on a range of objects

Recently I was in the situation to look at the GCRoot of a bunch of objects in a range.
Eran posted on how to do this taks for getting detailed object information. I used this as a template for my needs:

.foreach (obj { !DumpHeap -short start_address end_address }) { !GCRoot ${obj} }

Now replace start_address and end_address with your adresses...
