"concurrent.futures.as_completed() memory inefficiency" hum, sadly the commit 97e1b1c81458d2109b2ffed32ffa1eb643a6c3b9 introduced a reference leak. Example:

$ ./python -m test -R 3:3 -test_concurrent_futures -m test.test_concurrent_futures.ProcessPoolAsCompletedTests.test_zero_timeout
(...)
test_concurrent_futures leaked [27, 27, 27] references, sum=81
test_concurrent_futures leaked [16, 17, 16] memory blocks, sum=49
(...)
