New submission from Donny Brown :
Starting multiprocessing.Process causes FileNotFoundError in certain case:
```
import multiprocessing as mp
import time
def demo(f):
print(f)
def main():
cxt=mp.get_context('spawn')
f=cxt.Value('i', 0)
p=cxt.Process(target=demo, args=[f])
p.start()
return p
if __name__ == "__main__":
p=main()
p.join()
```
In this example, 'f' is supposed to stay in memory since it is referred by
p._args. However, starting the process raises FileNotFoundError once there is
not explicit reference to the arguments passed to the new process in the
original process.
