Ok, What does it mean to you the priority list?
For me, it means the order the results will appear in the screen.
The processing, I suppose it will fast enough so users will not bother
prioritizing it (or KDE should do the job transparently to the user). And
don't try to explain about other results coming earlier than the prioritized
ones in a multicore machine in bugs reports that's what it processing
priority is what it is meant for priority.

Also, for people be really be productive with a interface, the interface
must disappear and let then focus in the work. And to make the interface
disappear it should be subconsciously managed (as when you drive a car).
So,  answers to a given query should be always the same and in the same
order.

So I argued about sending things to the queue ordered, we will get them
disordered even if we try hard but surely this is the most efficient way. We
take the results and present to the user.

Now I just discovered a big problem in this idea. The results will be
created and recreated so what it is now the second result may not be the
second one when the user goes click it ... And wait for all the results
being ready is not an option either.

Maybe priority list is not so good idea anyway ...

What do you think about blacklisting being better than whilelisting?

To study what?
Japan is pretty much "go and try it". There are people who loves it and
people that hates it.
Living is comfortable and convenient but your everyday life will really
depend on where you live.
Oosaka University has at least two campuses I am aware of. Both are in the
north part of Osaka. It is a quite place there,  you can just use your
bicycle to go shopping, etc. And you have a cool monorail that connects to
the main railways.
If you prefer chaos and movement I guess it is not a good option.

Where are you?
