Note that a heap implementation for manual allocation and manual freeing isn't free of problem cases either. The heap will impose an accumulating maintenance overhead that will need to be cleared out eventually. Similarly to a GC heap you can try to amortize the overhead into some controllable, bounded chunks of computation but that doesn't mean pathological cases wouldn't exist nor happen.
