Yes.  I used sys.getobjects() API which is available only in pydebug mode.
Since it adds two words to all objects for doubly linked list,  I did
sys.getsizeof(o) - 16
when calculating memory used by each type.

While it may bit different from --without-pydebug, I believe it's
useful enough to
estimate how much memory is used by each types.
