Hum, even with the PEP 393, this string is still large: 682 MB.
$ python3
Python 3.4.1 (default, Nov 3 2014, 14:38:10)
>>> sys.getsizeof("�"*(2**32//12 + 1)) / 1024.**2
682.6667385101318
I guess that Serhiy suggests to put a @bigmemtest decorator on
test_case_operation_overflow().
The test expects that large_string.upper() raises immediatly an OverflowError,
so I understand that a new string is not created.
Hum, it's strange to have an OverflowError here. Integer overflow on memory
allocation usually raises MemoryError, not OverflowError. It looks like
unicodeobject.c is not consistent here.
