[issue12778] JSON-serializing a large container takes too much memory

[poq]

True, but that would just special case dump(), just like dumps() is special-cased now. Ideally JSONEncoder.iterencode() would be accelerated, so you wouldn't need any special cases. Or deprecate iterencode() and replace it with a callback interface...
