The problem occurs because entityform_views_pre_view() is executed each batch segment rather than once per export.
_entityform_view_add_all_fields() is then fired off for each batch and adds the fields without checking if they're already present.

imclean commentedThanks tedbow, patch applies cleanly and works well. I've successfully exported 500+ submissions with around 120 fields each in a minute with no duplicates.
Just a note that the first problem was the PHP process running out of memory.
This was circumvented by using paging (offset + specified number of items) and smaller segment sizes of 1 to 3. Only then were we able export the CSV and see the duplicate fields.
