I have observed it caught failure at the very first run. However I could not fail t again. I tried running up to 20 instances, with 1 or 2 active cores (that's all I have here), also edited the test to include only push_plain case, and repeat it several times, to avoid running irrelevant cases, the failure never happened again. The first failure was a bit unusual, in the ouput actually all tests were marked as passed, but it still failed somehow. Unfortunately, I did not save the output. I submitted the perl patch -- Max
