Neat, thanks.

I am wondering why [3] is not getting triggered and cleaning up the 
files in your test run. It seems to be doing the job in my setup. 
Possibly something to check/debug when you get a chance.

This should be fine for the exercise. The interest in running a test 
more than once is to ensure we do not have any noise from a single run 
that gives us incorrect numbers as a result. So for now, running this 
once is fine, unless you get some time to debug as above.

I would encourage looking at the next part (i.e tools to analyze the 
system) of this task, as that can provide some more meaningful data for 
the project.

[3] GlusterBench line that should cleanup small files:
