Since the D-Bus server daemon works using Unix sockets, it's possible to
use the SO_PEERCRED getsockopt() call to retrieve the peer's identity,
including UID and PID.
But note that this only works on Unix sockets. If your D-Bus daemon is
offering access via any other protocol (like TCP/IP), you may get an
unreliable behaviour, since the daemon cannot determine the PID of the

Well, the callee is you. Why do you want to have such a calltree?
Or is this an external process that is eavesdropping and trying to provide
timing & profiling for D-Bus calls?
