This is strange because for me tests on linux run ok. And I run them a 
lot because I test every commit. Anyway it could be the configuration 
difference, like the number of CPUs. I'll exclude the tests now, but I 
think the idea of having a local CC exclude list in the other thread is 
a good one. This way CC will be stable while we'll still see test 
failures and will work on fixing them.
