Yes, thanks Mark!  Please say in the commit message that I approved it.

Brett, Neal and I spent several hours this evening trying to track  
down the test_profile failure, but we were unsuccessful.  We suspect  
it's due to a call from C that eventually ends up in StringIO.flush()  
but we were unable to find it.  I'm going to disable this test for the  
3.0 release; someone else is going to have to fix it.

BTW, I am on #python-dev now if anybody wants to help and/or chat  
about the release. I'm also on IM and Jabber.
