Description of problem: As of today, for the unit test framework, there is no 'configurable' options to introduce the delay into the fops without making changes in the code, which stops us from automating some of the race-case situations. Having a translator to do this job would be very desirable. The request raised due to the problems of writing a test cases for scenarios like http://review.gluster.org/3730 One of the comment from Avati: "It would be handy to have a "debug/delay" translator where we can induce artificial delays (using timer thread) in the unwind path for specific (type) of fops (just like how error-gen errors specific types of fops) and expose the vulnerability window"
