by Pau Espin Pedroltests/osmo_io: Introduce small sleeps waiting for read completion
Sometimes test_file() fails during jenkins run because it finished the
main loop iterations without having received a read complete cb.
This may be due to filesystem delays due to system load, it's difficult
to say since it only happens sporadically.
Add some small sleeps under each loop iteration (which can end up
waiting up to 10s after full set of iterations) to make sure we receive
the read callback in a timely fashion.
