- protect smaller apps from bigger memory hogs

Why? Yes, it's very altruistic, very sportsmanlike, but giving small,
rarely used processes a form of social security is only going to
increase bureaucracy ;-)

It is critically important that when under memory pressure, a
system administrator can still log in and kill any runaway
processes.  The smaller apps in question here are system daemons
such as init, inetd and telnetd, and user apps such as bash and
ps.  We _must_ be able to allow them to make at least some
progress while the VM is under load.

Also, the memory space used by these small apps is usually
negligable compared to the memory used by the big program.

What is 2% memory use for the big program can be the difference
between running and crawling for something like bash...

Rik
