+* implement Distribute= in socket units to allow running multiple
+ service instances processing the listening socket, and open this up
+ for ReusePort=
+
+* add a timelimit to generator invocation
+
+* socket units: support creating sockets in different namespace,
+ opening it up for JoinsNamespaceOf=. This would require to fork off
+ a tiny process that joins the namespace and creates/binds the socket
+ and passes this back to PID1 via SCM_RIGHTS. This also could be used
+ to allow Chown/chgrp on sockets without requiring NSS in PID 1.

+* New service property: maximum CPU and wallclock runtime for a service
