Generally the code looks good, there is still a minor difference between
C API and this changes though. As we do call the _tst_cleanup_timer at
the end of this function the script runs without a timeout for a short
while (which includes tst_mkfs call).

I guess that instead of stopping the timer at the end of the
_tst_run_iterations() we can simply reset it (on the top of this patch):
