According to Martin, OpenBSD doesn't implement POSIX semaphores.
I don't have an installation of OpenBSD, but...

In FreeBSD, POSIX semaphores are implemented in sys/kern/uipc_sem.c.

that file doesn't exist. Also, in FreeBSD's limits.h,
_POSIX_SEM_NSEMS_MAX is defined (surprisingly to 256);

this constant doesn't appear. So ISTM that OpenBSD doesn't implement
POSIX semaphores. IIUC, this means that the multiprocessing module
won't be fully functional, and its tests (and the concurrent.futures
tests) will be skipped.
