Ok, please disable the test for now, I have more important things to do for the beta :)

Oh. Sorry, I didn't mean to assign it to you anyway.

(the fix is probably trivial, it involves dividing sys.maxsize by the number of bytes of an unicode character, something like: width = sys.getsizeof("a") - sys.getsizeof("") alloc = lambda: u"a" * (sys.maxsize // width) self.assertRaises(MemoryError, alloc) self.assertRaises(MemoryError, alloc) you can give it a try if you want ;-))

This patch is ok on both UCS2 and UCS4 builds (on 32-bit machines). Someone should test it on a 64-bit machine.
