I don't have much of a solution, though I have a question: if you use the existing functions with the additional argument, you should be able to make sure that the number of cells never drops below a certain threshold. And while the function doesn't *guarantee* this number, it probably shouldn't create more than, say, 20% more cells than you wanted. So, if for example you set the refinement threshold to 30% and the coarsening threshold to 70%, shouldn't you always get meshes that are at most 20% over the limit, uniformly over all time steps?
