have a look at '/usr/src/linux/Documentation/sysctl/vm.txt'.  thinking that some
of the settings may be of use (eg admin_reserve_kbytes, overcommit_memory, the
cache stuff).

sticking my neck out -- the majority of those terminals will 'ssh' sessions?  in
which case, if you're not familiar/having considered already, a single (u)xterm
running screen(1) could take care of those.  v convenient ime, detachable
sessions etc, "old" s/ware, ie stable.

(six "virtual" desktops, here.  nowhere near as many terminal session though

am somewhat interested because I've enabled the pre-installed Linux VM on the
Chromebook, and that is Debian/Ubuntu, though no gnome desktop.
