ServiceOwnerChanged wakes up everybody?

[Kimmo.Hamalainen at nokia.com]

Hi,

We were monitoring processes' CPU usage in the coming Nokia 770
internet tablet that extensively uses D-BUS and we found that
every process on the bus is woken up when some process enters
or leaves the bus. So it seems that the ServiceOwnerChanged,
and ServiceDeleted signals are always delivered to everybody
even if they are not AddMatched for. Is this a bug or desirable
behaviour? I think 95% of the processes don't use this information.

BR, Kimmo
