    4    bit bigger than _fmutex metaphores but they are inherited by child
    5    processes created with fork().  Shared _rmutex semaphores behave
    6    like _fmutex semaphores, ie, they are not registered and therefore
    7    not inherited by child processes created with fork().  (As malloc()
    8    uses _rmutex semaphores, we have to support shared semaphores
