Francios, Slavek, Michele, E.

  Depending on the difficulty this fix requires, this may be one we want to fix before R14. It effects every install and the sheer volume of clock-cycles being consumed when TDE is sitting idle is alarming. Get Tim's input, but I think we need a bug report opened at either critical or blocker (you guys make the call). I'm in Colorado this week and have limited time over the next 6 days. I get the trinity-devel list, but my replies must be sent via my ISP's webmail interface (not good). Keep up the great work. Michele, if the consensus is to open a bug report on this one - can you do that this time?
