 Log Message:
 Add makeshift NetBSD support using POSIX semaphores.
 Not upstreamed because I think NetBSD should be given the chance to
 implement some better interprocess synchronization primitives first.
 See PR lib/49529.
 In particular what's missing is an interprocess sync primitive that can:
   1) be passed safely through MAP_SHARED memory
   2) support atomic unlock-and-block (like pthread_cond_wait)
   3) wake up all waiters at once
