sorry for late response. (I didn't notice your mail ;-)
You are right... stupid user space caching is very important problem.
but I think this is no libc problem. glibc malloc hardly caches the memory. (its default behavior only caching 128K.)
but some application use large memory for too opportunistic caching. I understood we need propagandize that using mem_notify to application guys after it merge mainline.
I have no idea of solve it easily.
