Just want to add the following. I started a 'rpm --rebuild
kernel.src.rpm' (with an active gnome desktop & mozilla - and at the
end of the build - I have)
# free
total used free shared buffers cached
Mem: 1034568 488668 545900 0 44296 272364
-/+ buffers/cache: 172008 862560
Swap: 2096440 176 2096264
# slabtop
OBJS ACTIVE USE OBJ SIZE SLABS OBJ/SLAB CACHE SIZE NAME
2660 874 32% 0.68K 532 5 2128K ext3_inode_cache

So the kernel frees ext3_inode_cache memory once a big (high i/o
usage?) job starts up. i.e the memory usage behavior looks ok to me.
