> The free disk variable based suggester can stop generating suggestions too 
> early because it short circuits the suggestion loop after the first node that 
> results in a violation (or increases the violation).
> This is further exacerbated by the fact that the replicas in each node are 
> evaluated in the order of index size ascending which causes the smallest 
> replicas to be considered first. If a violation happens in moving this small 
> replica then the larger replicas are never even considered for a move.
> We should consider all possibilities here and stop short circuiting on a 
> violation.
