Multiprocessing Bomb
- by iKarampa
I was working the following example from Doug Hellmann tutorial on multiprocessing:
import multiprocessing
def worker():
"""worker function"""
print 'Worker'
return
if __name__ == '__main__':
jobs = []
for i in range(5):
p = multiprocessing.Process(target=worker)
jobs.append(p)
p.start()
When I tried to run it outside the if statement:
import multiprocessing
def worker():
"""worker function"""
print 'Worker'
jobs = []
for i in range(5):
p = multiprocessing.Process(target=worker)
jobs.append(p)
p.start()
It started spawning processes non-stop, without any way of to terminating it. Why would that happen? Why it did not generate 5 processes and exit? Why do I need the if statement?
