It'd be nice, but just try grabbing 2mb of kernel memory at once
section... it doesn't seem that the kernel allocates it like that.  (am
I missing something)?

However, I do believe that bumping it up to 64k or so would bring us nearly 
on par with playcenter etc.  I'm currently doing this with uploading,
(see the "block_cache" code in proc.c in my branch) and the njb 
can't keep up. =)

It'd be fairly easy to apply the same principal to downloads, although
perhaps a bit trickier.

This bit is pretty much done in my branch.  check it out.
