  Modified files:
    sys/vm               vm_map.c 
  Log:
  When creating a shadow vm_object in vmspace_fork(), only one
  reference count was transferred to the new object, but both the
  new and the old map entries had pointers to the new object.
  Correct this by transferring the second reference.
  
  This fixes a panic that can occur when mmap(2) is used with the
  MAP_INHERIT flag.
