Features:
+* libsystemd-journal returns the object created as first param in sd_journal_new(), sd_bus_new() and suchlike as last...
+
* cgroups:
- implement system-wide DefaultCPUAccounting=1 switch (and similar for blockio, memory?)
- implement per-slice CPUFairScheduling=1 switch
but do not return anything up to the event loop caller. Instead
add parameter to sd_event_request_quit() to take retval. This way
errors rippling upwards are the option, not the default
- - native support for watchdog stuff
+ - event sources should not be able to keep the sd_event around unconditionally
* in the final killing spree, detect processes from the root directory, and
complain loudly if they have argv[0][0] == '@' set.
