Thanks for the input! It looks like on hydra the failure is
reproducible. I would therefore tend to discard randomized tests. Do
you happen to know the timeout for tests? The test fails after
17seconds which is not very long.
Now that you mention race conditions, I remember having a hard time
with parallel builds in ATLAS; and numpy makes use of it. I may try
adding '#:parallel-tests? #f'.
Thanks,
Fede
