E.g. say Unicode gets interned someday, then resize will need to watch out not resizing a Unicode object which is already stored in the interning dict.
Note that string objects deal with this by requiring that the reference count is 1 when a string is resized. This effectively enforces that resizes are only used when the original creator is still working on the string. --Guido van Rossum (home page: http://www.python.org/~guido/)
