Indeed, I am on OSX. Yes, I have read the comment for the test. Would the
following pseudocode be an acceptable fix for the problem:
if sys.platform == 'darwin' and math.sqrt(-1) == nan:
     return
else:
  try:
     x = math.sqrt(-1)
  except ValueError:
     pass
  ...
or should I just not bother?
