[issue9903] test_concurrent_futures writes on stderr

[Antoine Pitrou]

New submission from Antoine Pitrou <pitrou at free.fr>:

test_concurrent_futures writes the following on stderr:

exception calling callback for <Future at 0x6a72508 state=finished returned int>
Traceback (most recent call last):
  File "/Users/buildbot/buildarea/3.x.parc-leopard-1/build/Lib/concurrent/futures/_base.py", line 267, in _invoke_callbacks
    callback(self)
  File "/Users/buildbot/buildarea/3.x.parc-leopard-1/build/Lib/test/test_concurrent_futures.py", line 626, in raising_fn
    raise Exception('doh!')
Exception: doh!


test_concurrent_futures should capture stderr instead, and also probably check its value (to be sure that the exception does get logged out properly).
