But that was not the question. What about the status of the buffer function?

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.
