Strange behavior of Python multiprocessing package

The following lines works without issue inside a regular python but not inside pvpython.

>>> import multiprocessing as mp
>>> p = mp.Process(target=print, args=["Hello"])
>>> p.start()
>>> Hello

>>>

With pvpython we get the following error

>>> import multiprocessing as mp
>>> p = mp.Process(target=print, args=["Hello"])
>>> p.start()
