I think the part of the test that tests the stats after resetting it
might give different results. This can happen because in the previous
test we spill multiple times (spill_count is 12 in my testing) and it
is possible that some of the spill stats messages is received by stats
collector after the reset message. If this theory is correct then it
better that we remove the test for reset stats and the test after it
"decode and check stats again.". This is not directly related to your
patch or buildfarm failure but I guess this can happen and we might
see such a failure in future.
