--- Comment #1 from François Gouget  ---
I checked whether the tryok() mechanism could help with this test but it does
not: if these two ok() calls fail, then they continue failing on the current
process even if retrying for the next 10 seconds.

So the question is why do these tests fail, sometimes and can anything be done
to avoid failure?
