Oh, I almost forgot... Right now I've googled up and am reading this 
intro: http://www-rp.lip6.fr/~sf/WebSF/PapersWeb/iscc01.ps

So turning to GRED would turn my FreeBSD router from dumb into a smart 
router that knows TCP? I thought pushing bits around at a lower level, 
and a sufficient queue size were enough.
Still not sure why increasing queue size as high as I want doesn't 
completely eliminate drops.
