  I don't even think that much is right.  Any time the kernel does
I/O, it uses buffers.  Even if you can find some way to cause the
kernel to "free" them all, it will immediately need to allocate new
ones for every I/O operation it does after that.  And it will cache
those all over again, too.

  Isn't debugging what engineers are for?  ;-)
