of data written. Whereas in libaio, there can be a huge difference between
the two (up to 2-3 times the other). This is consistent.
Besides that, GUASI performance follows pretty much the libaio one, up to

Fix bug with numjobs > 1, directory and filename given

Reported by gurudas pai <gurudas.pai@oracle.com>

If numjobs > 1, add_job() will append the directory name
several times. Fix this by doing the directory append in
add_file() instead, it cleans up the code as well.
