I have always wondered why the default for the rsize and wsize has not
been set to 8192 now? I remember the limits for the 1k block sizes
were there when Linux couldn't allocate buffers bigger than some limit
I don't remember right now (4096 bytes - headers?). This restriction
went away with the new kmalloc code (written by Alex Bligh?).
