guys there's a fix. i have a 2013 mba. the problem is in applehda. you can look at the hpet shoot up after sleep using `powermetrics` here's a video to reproduce the issue http://youtu.be/Q8OqdMq98j4 http://youtu.be/Q8OqdMq98j4 and here's a dmg that has the fix. basically it replaces applehda with the one from 10.8.5 http://puu.sh/5RBvj.dmg http://puu.sh/5RBvj.dmg i've been using it happily for ten days. some people claimed it wouldn't work with haswell, but it does for me. YMMV though
