Yet Another Tool ;-) Python's "small object" allocator grabs memory in chunks of 256KB from the system, and carves up the space itself. Other memory tools (like Valgrind ...) only see that Python has grabbed 256KB chunks, so can't detect anything wrong _within_ those large blocks. For that reason, compiling Python --without-pymalloc usually increases the usefulness of other tools.
