It seems to take an awfully long time which would suggest it is infact doing that.

You mentioned it before I got back from work..
Yup, that's what "Secure Empty Trash" does -- writes over the data in multiple passes, scrambling it to Department of Defense standards for erased data. The regular "Empty Trash" command just deletes it out of the index, effectively putting a "1" in front of the file. That's why someone can recover files that you "deleted" just by choosing Empty Trash.
This was a noteworthy item when Panther came out. I'm surprised that it's not common knowledge by now.
