- kdbus: matches against source or destination pids for an "strace -p"-like feel. Problem: The PID info needs to be available in userspace too...
- kdbus: we need a way to distuingish messages we got due to monitoring from normal messages, since we want to bind methods only to the latter
- kdbus: when we do "systemctl daemon-reexec" the call doesn't get properly cancelled
- - figure out what to do when fields in the kdbus header and in the payload header do not match
- longer term:
* priority queues
* priority inheritance
- - fix sd-event hookup when we connect to multiple servers one after the other
* sd-event
- allow multiple signal handlers per signal?
