I also found this to be a general issue with file cache taking too
much room on desktop systems (but being generally fine for servers)...
 So on my desktops I also modify vm parameters to allow more
executable pages and less file cache ones which helps a bit.  Without
it applications would get swapped out often during operations such as
cvs update or nightly find runs, and I would notice the file cache
grow to ridiculous proportions (for a desktop system at least).
