Why would you want to stop disk writes? The kernel can easily _read_
data (when it has free buffers) even when it pushes out dirty
buffers in a tight loop. The problem is that you don't have
free buffers because all are occupied by data that needs to
be written. Stopping the writes won't free any buffer.
