[issue43145] Leak of locks in a subprocess

[Boris Staletic]

Slightly simpler C example:

#include <Python.h>

int main()
{
        Py_Initialize();
        PyObject* multiprocessing = PyImport_ImportModule("multiprocessing");
        PyObject* Process = PyObject_GetAttrString(multiprocessing, "Process");

        PyObject* p = PyObject_CallNoArgs(Process);
        PyObject* start = PyObject_GetAttrString(p, "start");
        PyObject* join = PyObject_GetAttrString(p, "join");

        Py_DECREF(PyObject_CallNoArgs(start));
        Py_DECREF(PyObject_CallNoArgs(join));

        Py_DECREF(join);
        Py_DECREF(start);
        Py_DECREF(p);
        Py_DECREF(Process);
        Py_DECREF(multiprocessing);
        Py_Finalize();
}
