The elevator doesn't sort buffers, it only sorts requests --- and
there is a strict limit on how many requests we can have outstanding
at once. I wouldn't have thought that elevator scalability would
have had anything to do with performance going downhill above 3000
buffers.
Only profiling will tell, of course...
