[issue15781] test_threaded_import fails with -j4

[Stefan Krah]

Stefan Krah added the comment:

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.
