__del__ in Python is complicated. I'm not sure what is the correct way to
use it. I only know that if you want to release resource, you should call
close(), free(), release(), Destroy() or whatever is the name. One doesn't
call __del__() explicitly on the object itself.

No, each case might be different. Although some revision might be useful,
there is no other case where object would call __del__ on itself
(`self.__del__`):

grep -Irn "self.__del__"

But what might be happening in the current code is that the resources are
not released but that requires case-by-case investigation.
