-------------------------------------------------------------
I did successfully reproduced the error locally. The error occurred only once
in 100+ runs. I compare its output with the successful outputs but cannot find
any big difference, other than the exit code. I also tried to rerun the failed
test by setting the PYTHONHASHSEED value, which is a source of indeterminism,
but it doesn't help to to reproduce the failure. So my guess is that something
like a race condition in Nose is the root of the bug.
I have also found that the last change made in the Nose project was almost 3
years ago.
