Charles-Francois Natali <neologix at free.fr> added the comment:
The most obvious explanation for that failure is that the barrier's timeout is too low.
def test_default_timeout(self):
"""
Test the barrier's default timeout
"""
#create a barrier with a low default timeout
barrier = self.barriertype(self.N, timeout=0.1)
If the last thread waits on the barrier more than 0.1s after the first thread, then you'll get a BrokenBarrierError.
A 0.1s delay is not that much, 100ms was the default quantum with Linux O(1) scheduler...
