httpd isn't going to stay completely in memory at all times, there is
no need it would be wasteful especially if the myraid of aspects of
httpd are not used by the running process. however because it has many
workers and sub processes and what not it does swap in and out a lot
and has a ton of activity (though likely minor impact) on this front.

ten million or so pagefaults isn't a big thing for a very sub process
intensive program (like explorer for example).
