+ * #GMemoryMonitor will monitor system memory and suggest to the application
+ * when to free memory so as to leave more room for other applications.
+ * It is implemented on Linux using the [Low Memory 
Monitor](https://gitlab.freedesktop.org/hadess/low-memory-monitor/)
+ * ([API documentation](https://hadess.pages.freedesktop.org/low-memory-monitor/)).
+ *
+ * There is also an implementation for use inside Flatpak sandboxes.
+ *
+ * Possible actions to take when the signal is received are:
+ * - Free caches
+ * - Save files that haven't been looked at in a while to disk, ready to be reopened when needed
+ * - Run a garbage collection cycle
+ * - Try and compress fragmented allocations
+ * - Exit on idle if the process has no reason to stay around
+ *
+ * See #GMemoryMonitorWarningLevel for details on the various warning levels.
