Incidentally, the new array will be read-only. But, you can fix this in
1) a.flags.writeable = True
--- This is a cheat that avoids the extra copy on pickle-load and
let's you use strings as writeable buffers. Don't abuse it. It will
disappear once Python 3k has a proper bytes type.
2) a = a.copy()
