/**
 * #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.

 * signal, and unref the #GMemoryMonitor itself when exiting.
