We absolutely need this.  People will complain left and right if it 
isn't "just" working.

Probably I'm missing something, but can't we reserve N blocks for 
reblocking purposes, so that the reblocker always can make progress?

Why wouldn't the reblocker anyways start with the almost empty blocks? 
Which order is it picking right now?
