Ultimate Solution 
Open your MAC Drive where you install OS X Yosemite and navigate the following System/Library/LaunchAgents
and “move” the following files to secure folders if any go wrong so you can restore it
  • com.apple.UserEventAgent-LoginWindow.plist
  • com.apple.UserEventAgent-Aqua.plist
MAC OS X will ask you for admin Authentication type your super
scared password
 
Once done. Reboot your System and see the effect, HIGH CPU usage by UserEventAgent should be gone
Note:-This Guide is tested on Real MAC System(Macbook Pro) and Hackintosh System with following OS X Versions Developer Preview (DP 1),(DP 2),(DP 3),(DP 4) and this bug is Fixed in MAC OS X Yosemite Public Beta Version.
