(ie. it's largely free()d memory that malloc() cannot return to the operating system) That shouldn't cause memory pressure issues since over-commit will already take care of that.

You can obviously cause the dbus-daemon to increase its memory usage by sending a vast volume of messages, but massif shows it as freed memory afterwards.
