Async call handling is the only way to (possibly) totally avoid
deadlock, any other scheme leads to subtle deadlock cases (see mailing
list history for a discussion of this, in respect to DCOP deadlock
breaking).

Note that only code providing objects on the bus needs to use async
calling, normal clients can still use synchronous calls.
