Could that lead to KMail not reacting to user input. I.e. when switching 
folders quickly?

I think it would make sense to cancel previous action then, but especially 
when synchronizing I have seen KMail / Akonadi taking lots of time (>10-20 
seconds or possibly even a minute) to display a mail I click on.

I think that for good user experience it is important to prioritize the most 
recent user query over background tasks. Cause I think that Akonadi was made 
to enable KMail to react to user queries no matter whats going on in the 
background. I thought this, aside with having mutiple clients using same 
framework, was one of the main motivations behind Akonadi. But now with using 
KDEPIM 4.10.4 SC I see KMail 2 occasionally block just like KMail 1. Well 
unlike KMail 1 the GUI is not completely blocked, but if any action I take 
gives me a "retrieving" message the difference is not that huge.

I as user expect quick response at the task I currently put my focus on and 
there I think KMail 2 sometimes still lacks responsiveness.
