This issue was merged with #478, which is marked as fixed. But for me, this 
Issue isn't fixed!
I checked out latest master (2013-10-05 06:35:05 
345fed9dcbde0dec3d330c89939cb9372324832e) and build it with yoxos eclipse.
The cpu load still goes up to 100% on one core.

Same 100% CPU experienced here with OH 1.4.0.
