The file cache in Linux will eventually use all available memory.
I'm not sure what you mean by committed memory... but the file cache 
does write dirty blocks within a few seconds.  So the pages in memory 
aren't dirty.
It's pretty cool - when I edit & compile a large project, Linux rarely 
hits the harddrive - all the code, libs, etc are cached in memory.  That 
makes for a very fast compile. =)
