BUG#12427262 : 60961: SHOW TABLES VERY SLOW WHEN NOT IN SYSTEM DISK CACHE

Details:
 - test case bug12427262.test was failing on windows because
   on windows '/' was not recognized. And this was used in
   LIKE clause of the query being run in this test case.

Fix:
 - Windows needs '\\\\' for path seperater in mysql. I was 
   not sure how to keep a single query with two different 
   syntax based on platform. So modifying query to make sure
   it runs correctly on both platform.
