[Numpy-discussion] unittest for np.random.poisson with lambda=0

maybe this is an obsolete concern,
but at some point in the past
N.random.poisson would not always return 0 for lambda being zero.
(My post at the time should be in the (numarray)  list archive)

So the question is, is this still a valid concern for the current numpy?
Could there a unittest added that does something like this:

>>> a=N.random.poisson(0, 10000)
>>> N.alltrue(a==0)
