Sure, 

but in other cases it is a bad idea to use non blocking querys.  

Just there were there is no need to use it non blocking. ( I believe the data 
engine is such case (but not really sure about that)).  

Non blocking means extra overhead  in terms of cpu time, memory use and code. 
There are good reason to use it non blocking. (to have a responsive amarok and 
and a non freezing gui). But amarok is already doing a lot of things in extra 
threads just for the same reason. These threads should if possible use 
blocking querys.
