Depends on the test. For mocks, I think it's useful, when dealing with real platform code where the outcome will either be a spurious pass or a hang depending on the details, I think it's clearer to skip. Note that os.name == "posix" covers linux, bsd (which actually has a different signal interrupt paradigm but python switches into the posix style), mac os x, solaris... Name me a platform bzr supports that you're worried about skipping the test on?

I see you've now found:
