That person stopped working on it.  It is still on the TODO list.

This has me confused.  There was an exchange with Gavin Auguest 27/28
which resulted in a patch:


and my adding it to the patches list:


However, it was never applied.  I don't see any discussion refuting the
patch or any email removing it from the queue.  The only thing I can
think of is that somehow I didn't apply it.  

My only guess is that I said I was putting in the queue, but didn't. I
am concerned if there are any other patches I missed.  I see the cube
patch being added to the queue 40 seconds later, and I know that was in
there because I see the message removing it from the queue.  I must have
made a mistake on that one.

What do we do now?  The author clearly got it in before beta, but we are
in beta now.   I think we should apply it.
