The concurrent.futures tests should (like the multiprocessing test suite) detect the lack of support and skip the tests on the broken platforms. I'm sort of surprised FreeBSD support is still broken in this way though (echoed by Philip) although it could be an issue on that particular buildbot.
If I'm reading the issue correctly, it isn't that it doesn't work, it's that the concurrent.futures tests fail because they create more semaphores than the default FreeBSD install supports. In other words, a user of concurrent.futures really needs to tweak their FreeBSD install to make in fully functional.
There should be a way (through sysctl, presumably) to query the maximum number of semaphores and skip the relevant tests on that basis.
