Of course the test fails: a process can't have a nice value higher than a certain limit, which I think can vary depending on the UNIX variant in use. The fix is not to use "nice -n20". |

I actually wanted to use 'nice -n19 python3.3 -m test.test_os', which also fails. Test suite of Python can be run be a package manager, which automatically sets high niceness. If niceness is high, then maybe this test could try to decrease it instead of increasing. |

> If niceness is high, then maybe this test could try to decrease it instead of increasing. You must be root or have CAP_SYS_NICE to do that. |

We could, however, raise SkipTest if getpriority returns 19 or higher with a message like "unable to reliably test setpriority at current nice level of NN". My guess is that no system we support has a lower upper limit on nice. If someone wants to customize the test/message per OS, that would probably be even better; but not, I think, required. |

To be clear: raise SkipTest if prio is 19 or above *and* the increment fails. |
