 world maps and click Africa (a PDF), another full copy of the PDF is added
 to ~olpc/.sugar/default/datastore/store by Read activity 45.  If I read
 this bug correctly, that behavior is a downside of this bug fix.

 Actually, that's nothing to do with Read - if you click on a PDF in
 Browse, then the download will create a new datastore entry with a new
 copy of the file before you even think of opening Read.

 Every OS I've seen will create a duplicate file if you download the same
 thing twice.

 There is a chance to improve this with the next generation datastore,
 though, if we use hard links and copy-on-write. I'm logging a new ticket
 to track that, so it doesn't get confused with Read - see #8155.

 In the mean time, I'm closing this ticket to prevent confusion with
 existing Read issues.
