Full-blown GNOME Desktop shows in GNOME System Monitor as consuming <390
MiB of RAM. Opening the arstechica.com Web site in netsurf-gtk makes for
a total of <490 MiB.

Note that top can distinguish between „readily reclaimable“ memory and
memory that is not „readily reclaimable“, which AFAIK is what is
actually important. See the top man page.
