Mnesia - 2Gb or 4Gb - which is it?

Hi guys,

I'm trying to figure out the table limit with Mnesia.

If I read this document
http://www.erlang.org/doc/man/dets.html

I get the following:
The size of Dets files cannot exceed 2 GB.

However, if I read this document
http://erlang.org/faq/mnesia.html

I see this in section 11.5
Dets uses 32 bit integers for file offsets, so the largest possible mnesia
table (for now) is 4Gb.

Is this a documentation bug? Is there some weird inter-relation between
mnesia and dets that I'm not coming across?

Thx,
