So as I look at this and make various spot checks, what really stands 
out is how often something like alias.h gets included, often in places 
that have absolutely no business/need to be looking at that file. 
Cut-n-paste at its worst.  It happens to many others, but alias.h seems 
to have gotten its grubby self into just about everywhere for reasons 
unkonwn.

I find myself also wondering if a two step approach would make this 
easier.  Step #1 being ordering the headers, step #2 being removal of 
the duplicates.  As you note, the downside is two checkins that would 
affect most files in the tree.  I guess I'll keep slogging through the 
patch as is...
