I am trying to understand the multiprocessing module, and I tried some
simple code:
import multiprocessing
def f():
print('bla bla')
p = multiprocessing.Process(target=f)
p.start()
p.join()
And the result is a new process that spawns a new process that spawns a
new process ad infinitum until I log out and the OS forcefully
terminates all my user processes. I have no idea what is happening; I
expected it to just print the string and terminate.
Anything that runs at import time should be protected by the `if
__name__ == '__main__'` idiom as the children will import the __main__
module.

import multiprocessing
def f():
print('bla bla')
if __name__ == '__main__':
p = multiprocessing.Process(target=f)
p.start()
p.join()
