+pressure information coming from the kernel, and, when memory pressure means
+that memory isn't as readily available and would cause interactivity problems,
+ would:
+
+@itemize
+@item send D-Bus signals to user-space applications when memory is running low,
+
+@item if configured to do so and memory availability worsens, activate the
+ kernel's OOM killer.
+@end itemize
+
+It is designed for use on traditional Linux systems, with interactive user
+interfaces and D-Bus communication.")
