On the i7 machine with hyper-threading the issue occurs since edb9ce3a6c2e. The tests also got slower: 3430d7329a3b: $ time ./python -m test -uall -v test_threaded_import real 0m3.195s user 0m0.656s sys 0m0.284s edb9ce3a6c2e: $ time ./python -m test -uall -v test_threaded_import real 0m24.032s user 0m0.880s sys 0m0.744s Here most of the time is spent in test_parallel_meta_path. DISCLAIMER: This machine runs Debian Wheezy, which is not stable yet! On the other hand the Windows bot also reproduced the issue.
