Taking a wild guess, because w.close() doesn't actually free any memory.
Apparently deleting the "this" (of "self" in python) in C++ from inside a
method is a big No-No. w.close() probably cues up w for destruction by Qt the
next time Qt enters its event loop. Your code never enters the event loop, so
your w is never fully deleted.
