WordPress import/export is still pants

It still chokes on ‘large’ files due to causing massive blooms of memory consumption. The XML parser implementation used insists on loading the whole file at once. This is a recipe for PHP choking a modest VPS.

A WXR splitter (there are several) is pretty much required. Why doesn’t WordPress perform this task itself?

It’d also be nice if it did even very basic duplicate checking.
