I am not asking for your help to use python.
What I post here is to want to report a potential issue about multiprocessing module.

This issue is the default start method fork will not free the object, but other methods works normally.
When I change to use os.fork() APIs, it also could free object in child process.

So I think it is a bug that multiprocessing fork method doesn't free object in child process.
