This options allows to flush the image periodically during write tests.

This pattern could be a bit different - you wait requests to finish
and after that start flush. In this case there is no gain with my
patch ;)

You should treat flush as ordinary write request i.e. place
request immediately without waiting for writes to finish.
May be this could be specified as an operation mode.
