Wow.  Now that's bizarre.  Today I noticed Mythbackend running at 400% 
CPU (Quad core) and here I thought it was due the upgrade I did 
yesterday from 0.25-fixes to 0.25.2.  Did a search in this forum and saw 
this thread.  Ran the 'date' command above and instantly mythbackend 
went back to normal.

Thanks Ben (and Erik for confirming)!

+1 Fixed
