Nonono, bad idea. They are part of the buffer handling (there job is now
partially handled by kswapd). For more info see bdflush(8).

You see, Linux really is better ;). Seriously, is it more than a few
percent (ie rounding errors) ? If you think that it's a real bug, and not
just noise look in /usr/doc/procps-1.01-11/bugs (that's where I have it
anyway ;).

Anyway, it dosn't really belong on this list (it's only for kernel
related messages, tho at times there is more noise than signal ;).
