-- 
-- t'GI.Gio.Interfaces.MemoryMonitor.MemoryMonitor' 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 <https://gitlab.freedesktop.org/hadess/low-memory-monitor/ Low Memory Monitor>
-- (<https://hadess.pages.freedesktop.org/low-memory-monitor/ API documentation>).
-- 
-- 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
--  - Call <http://developer.gnome.org/gio/stable/man:malloc_trim `malloc_trim(3)`> to return cached heap pages to
--    the kernel (if supported by your libc)
-- 
-- Note that some actions may not always improve system performance, and so
-- should be profiled for your application. @malloc_trim()@, for example, may
-- make future heap allocations slower (due to releasing cached heap pages back
-- to the kernel).
-- 
-- See t'GI.Gio.Enums.MemoryMonitorWarningLevel' for details on the various warning levels.
