Um. Firefox' "configure" code explicitly checks the maximum number
of semaphores via sysconf(_SC_SEM_NSEMS_MAX) (that's in
python/futures/concurrent/futures/process.py l. 250). As far as I
can tell, in FreeBSD 10.3 that value is set by sysctl
p1003_1b.sem_nsems_max - so at least for the "old" FreeBSD, that
would be the way to go? (and it worked for me).
Further, the sem(4) manpage has no deprecation note...

Regards,
Christoph
