 By performance profiling in Internet Explorer 10, Firefox 17 and Chrome
 25, I found performance improvement in wp-admin/js/post.js, wp-includes/js
 /media-views.js and wp-includes/js/utils.js. Function clean() at line
 number 17 in post.js, function set() at line number 98 in util.js and
 function visibility() at line number 2767 in media-views.js can be
 improved with same functionality.

 I measured inclusive execution times of original code and improved code.
 The image is the result. The machine I used to measure execution times has
 Intel Core i5 1.6GHz CPU and 4GB RAM.

 I also attached a patch file.
