David, (not on v17) I've played around with large text, mostly for testing purposes. large texts (>150meg) - very easily cause massive slow downs when trying to append - can easily crash/hang 4D.
While the *limit* on text maybe 2gig (+/-) my experience is that you can not get anywhere near that and expect to be able to manipulate the text in any reasonable time. So.... whatever end strategy you use, I would suggest you place a limit on the size of the text and export (or whatever) at that point.
