I've heard conflicting talk about using wipe on a journalled filesystem.

I don't think it would help much to remount ext3 as ext2, since the journal 
would still be on the disk.

I'd suggest using a cryptographic filesystem and encrypted swap though, if 
you're worried about security.  Wiping the file won't help much if the data 
was just copied to your swap space anyway ;)
