dev-python/execnet-1.0.3 fails tests when PORTAGE_NICENESS is set to value different than 0.
Created attachment 216822 [details] execnet-1.0.3:20100118-180714.log Example with PORTAGE_NICENESS="7".
Fixed in cvs, thanks. Currently, I get some unrelated test failure, both with and without the new patch. This separate question is being investigated.
Have you sent the patch to upstream?
I have. No reply yet :-(
