[Errno 32] Broken pipe When Mapping Too Many Values #47
Description
First of all, thanks for that great backport. I am using it for the xfork package to support the 2.7 branch.
Unfortunately, there is something strange happening with this futures distribution which works perfectly fine with python3.4
from concurrent.futures import ProcessPoolExecutor
def calc(n):
with ProcessPoolExecutor() as pool:
results = pool.map(term, range(n))
return sum(results)
def term(x):
return x
print(calc(5000))
/usr/bin/python2.7 calc.py
12497500
Traceback (most recent call last):
File "/usr/lib/python2.7/multiprocessing/queues.py", line 266, in _feed
send(obj)
IOError: [Errno 32] Broken pipe
