It mostly affects the call() I assume, send() should return directly either

callAsync only works if the receiver uses a DCOP transaction to handle the
call. It returns to the caller once the receiver has started the transaction.
Since JuK doesn't handle DCOP calls at all, it will not start a DCOP
transaction either, if it were to use one.
I think that DBUS will be able to do that better.

No, I don't think so. DCOP doesn't have any thread support at all and I doubt
that simply adding a mutex will be enough to make it work.
