@Lars

bq. This is not the same as merge, right?

Sounds like it is.

bq. The region's data will be gone

This patch seems to copy the data from the deleted region up into the new hole-plugging region.  It doesn't seem to delete it.

As to your 1., 2., 3... yes, thats what this patch does only the operators and the classes are all named DeleteRegion* blah when what is happening is region merging.

I think its important to get the concept right else its going to confuse for ever after.

@Mubarak So, sounds like the command/api could also be named merge rather than deleteRegion (You are not actually deleting the data, is that right?)?
