Oh how dearly I would love that...
I have a huge app that operates on a large file (but both are a bit smaller than available memory, by maybe a hundred or two megs - enough for to keep the entire working set in RAM, anyway). I create these large files over and over (on another host, so cache does absolutely no good whatsoever, since we are streaming a read once), but don't delete the old ones, so they all remain in cache. So when I close one copy of the app, and open up a new one on a different file, when it comes time to allocate those several hundred megs, it rather blows away my mozilla or my X session(! -- since I need it to display the results) or my window manager, and keeps growing that cache.
