I really don't think it is our job to maintain a list of OS/versions
which work and don't work.
At best, multiprocessing when imported could try to create a single
semaphore, and raise an ImportError if such creating fails (which it
does, IIUC, under some old FreeBSDs without a specific kernel tweak).

I'm not sure concurrent.futures is the culprit, rather than
multiprocessing itself (or perhaps even some core Python functionality).
Actually, the threading-based part of concurrent.futures probably works
