Is there any reason to reset the pointer each time? I think that it is more 
reasonable to leave the pointer as it when adding to the list so it’d be 
possible to work with the list and adding new items to it when they’re 
available without losing the context.
What I’m trying to do is to start a job that will search in a large code base 
and to be able to work with the available results as they appear. I don’t want 
to wait for the entire search to complete. Now, when trying to call 
setqflist(…, ‘a’) from the job’s callback I can’t really work with the results 
that already arrived.
