New submission from STINNER Victor <vstinner at redhat.com>:

I bet that the leak was introduced by:

commit 6c6ddf97c402709713d668d0ed53836a7749ba99
Author: Pablo Galindo <Pablogsal at gmail.com>

    bpo-20104: Expose `posix_spawn` in the os module (GH-5109)
    
    Add os.posix_spawn to wrap the low level POSIX API of the same name.
    
    Contributed by Pablo Galindo.

IMHO this issue is easy to fix, so I suggest to leave it to new contributors, or the author of the change.
