Because the real change followed the pipe sysctl, which might
affect many things in the system.  We put page loaning in the
pipe code to help performance.  Obviously something has changed
for the worse--we should understand that.  It might make more
sense to mothball that option.

For the progress(1) change to allow different buffer sizes and
to default to 64k instead of 1k, see a post on tech-userlevel@.
