From what I understand, it is relatively safe as long as you don't
mutate an object while there is a buffer attached to it.

That is:

    import array
    a = array.array(...)
    b = buffer(a)
    for i in xrange(...):
        a.extend(a[:])
    print str(b)

... may cause you some problems (the a[:] bit was to pointer movement
movement on realloc).  Those problems will depend on your platform.
