    sys/kern             uipc_sem.c 
  Log:
  In sem_forkhook(), don't attempt to generate a copy of the process semaphore
  list on fork() if the process doesn't actually have references to any
  semaphores.  This avoids extra work, as well as potentially asking to
  allocate storage for 0 references.
