In Py2.4, array's became copyable, weak-referencable, and
got support for iterator arguments.  Real pickle support
wasn't added until Py2.5.  The above code fragment is a
by-product of pickle making an incorrect guess at how to
pickle arrays before real pickel support was added.  It is
not really a bug; rather, it begs for a feature that wasn't
added to later.

If it weren't a new feature, I would just backport the 2.5
pickle support.
