Hi all,

for race condition tests, I would like the possibility of ATF running
a test more than one time in a row. I have a couple of examples, where
the failure would show up with a frequency of 1 in 50 or 100 runs.

On the other hand, if it doesn't fit to the ATF design &
implementaton, I could live without it.

Best regards,
