emm, no,
That only deactivates the on-disk cache and has nothing to do with the kernel
caches&buffers. In fact, it has nothing to do with the kernel at all.
Deactivating the cache might be a good thing in certain situations, but it
usually just decreases performance. So it is usually a BAD THING(tm).
