dcopserver knows them all. The client/server concept has to solve the 
same thing, BTW.

dcopserver. The client/server concept has to... you know the rest ;-)

dcopserver? If not, then the user gets prompted b/c of the timeout. 
Either she will know the cause already ("of course, my korg crashed!"), 
or can do something about it. The client/server .. you know.

Yes.

It doesn't respond anymore?

Why should that stop the process from responding? Even now, I can type 
this email while performing a search and I think we agree that making 
all Kmail operations non-UI-blocking is a good thing to have in itself.

You know, I can't understand why those points should be arguments 
against CIA/4, while at the same time you propose a much more complex 
protocol where almost every method call can timeout due to the DCOP 
peer dying or performing an expensive, blocking task?

If these are your only concerns, then, hurray, we have a compromise 
solution!
