Confusion regarding Numeric array resizing

  I'm confused by the restriction on resizing arrays demonstrated below:

>>> from Numeric import array
>>> a = array([0])
>>> a.resize((2,))
>>> b = a
>>> a.resize((3,))
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
ValueError: cannot resize an array that has been referenced or is 
referencing another array in this way.  Use the resize function.
>>> del b
>>> a.resize((3,))
>>> a
array([0, 0, 0])

  This seems like an unnecessary restriction.  Is there a reason I'm 
missing for it to be in place?
