Just for the ones who are curious. The "problem" was just that I didn't
knew the exact definitions of buffer and cache.
"cache" is the cache for text segments of programs, e.g. /bin/ls would be
very likely be in this cache.
"buffer" is the cache for IO drivers, here my IDE disk drivers store physical
blocks without caring what data is in there.
So both are caches. (I thought buffers are stack+heap segements of running
processes)
