The fragmentation issue I think is overbaked. A lot of the academic work argues that there is pretty much no long term difference between first fit, best fit, and most of the clever algorithms (obviously stupid ones like "take the middle out of the biggest space allocator" do perform worse). For MMUless boxes fragmentation is a big issue but not for normal systems.
