In this case (remotecall_fetch), yes. but in the previous code which was similar to

```
  remotecall(shmmem_create_pid, () -> shm_unlink(shm_seg_name))  
  shm_seg_name = "" 
```

shm_seg_name was "" when the function actually got executed. So, I guess in the remotecall case, the extra closure is still required?
