2.4.20-pre3 included some elevator changes. I assume they are the
cause of this. Those changes have propagated into Alan's and Andrea's
kernels. Hence they have significantly impacted the responsiveness
of all mainstream 2.4 kernels under heavy writes.
(The -ck patch includes rmap14b which includes the read-latency2 thing)
